Degradation mechanism of norfloxacin in water using persulfate activated by BC@nZVI/Ni

In this work, biochar-supported nano zero-valent iron/nickel bimetallic composite (BC@nZVI/Ni) was synthesized using liquid phase reduction method and used to activate persulfate (PS) to degrade norfloxacin (NOR) in water. The synthesized BC@nZVI/Ni was characterized using scanning electron microscope (SEM), X-ray diffractometer (XRD) and X-ray photoelectron spectroscopy (XPS). The effects of various reaction parameters, such as mass ratio of nZVI/Ni to BC, PS concentration, initial pH value, temperature, humic acid and the inorganic anions on NOR degradation were investigated using the system of nZVI/Ni/PS. The results showed that the system of nZVI/Ni/PS showed the higher degradation efficiency. The quenching experiments and EPA analysis manifested that center dot SO4- was the predominant radical species in acidic and neutral conditions, while center dot OH played an important role in alkaline environment. Matrix-assisted laser desorption-ionization time of flight mass spectrometry (MALDI-TOF MS) analysis illustrated that NOR can be degraded through multiple routes, such as decarboxylation, defluorination and cleavage of piperazine ring in the presence of center dot SO4- and center dot OH. These results demonstrated that nZVI/Ni/PS process was a promising strategy for treating norfloxacin-containing wastewater.

Rapid degradation of ciprofloxacin over BiOCl: Insight into the molecular structure transformation and antibacterial activity elimination

Currently, the widespread usage of antibiotics brings great challenge to sustainable water environment due to the production of drug-resistant bacteria, the rapid and effective removal of antibiotics attracts more and more attention. Herein, a BiOCl microsphere prepared by a facile hydrolysis method via controlling the EG-H2O ratio was found to have unexpected photocatalytic activity for ciprofloxacin (CIP) removal. The photodegradation rate of CIP over optimal BiOCl-20 reached 92.9% in only 3 min of simulated sunlight irradiation, and the mineralization rate was 30.8% after 60 min reaction. The antibacterial tests of CIP solution under different irradiation minutes were evaluated using Escherichia coli (E. coli) as the model bacteria. The results indicated that CIP photodegradation intermediates had also certain antimicrobial potency, which could be eliminated almost completely after 3 min irradiation, although there still had some incompletely mineralized intermediates. In view of these results, the macroscopic degradation behavior of CIP over BiOCl-20 as well as the microscopic existence state and reaction behavior of the intermediates should be clarified. A ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) was employed for determination of CIP and its intermediates. Ten primary intermediates were separated and identified, and their corresponding molecular structures were elucidated. Three main photodegradation pathways were deduced, and the correlation between molecular structure transformation and antibacterial activity of CIP was established. Because of the destruction of piperazine ring and defluorination of quinolone ring, the antibacterial activity of the treated CIP solution was weakened or even eliminated. Finally, a possible photodegradation mechanism was proposed, the OVs, O-center dot(2)-, h(+) and (OH)-O-center dot played significant roles in the CIP photodegradation. This work does have great perspective for BiOCl potential application in CIP wastewater treatment.

Design, synthesis and biological evaluation of novel osthole-based derivatives as potential neuroprotective agents

A total of 26 compounds based on osthole skeleton were designed, synthesized. Their cytoprotective abilities of antioxidation, anti-inflammation and A beta(42)(Amyloid beta-protein 42)-induced neurotoxicity were evaluated by MTT assays. Mechanism of the action of selected compounds were investigated by molecular docking. AlogP, logS and blood-brain barrier (BBB) permeability of all these compounds were simulated by admetSAR. Most of the compounds showed better antioxidative and anti-inflammatory activities compared with osthole, especially OST7 and OST17. The compound OST7 showed relative high activity in neuroprotection against H2O2 (45.7 +/- 5.5%), oxygen glucose deprivation (64.6 +/- 4.8%) and A beta(42) (61.4 +/- 5.2%) at a low concentration of 10 mu M. EC50 of selected compounds were measured in both H2O2 and OGD induced cytotoxicity models. Moreover, NO inhibiting ability of OST17(50.4 +/- 7.1%) already surpassed the positive drug indomethacin. The structure activity relationship study indicated that introduction of piperazine group, tetrahydropyrrole group and aromatic amine group might be beneficial for enhancement of osthole neuroprotective properties. Molecular docking explained that the reason OST7 exhibited relatively stronger neuroprotection against A beta because of the greater area of interactions between molecule and target protein. OST7 and OST17 both provided novel methods to investigate osthole as anti-AD drugs.

Modeling the rate of corrosion of carbon steel using activated diethanolamine solutions for CO2 absorption

A mechanistic model is developed to investigate the influence of an activator on the corrosion rate of carbon steel in the absorption processes of carbon dioxide (CO2). Piperazine (PZ) is used as the activator in diethanolamine (DEA) aqueous solutions. The developed model for corrosion takes into consideration the effect of fluid flow, transfer of charge and diffusion of oxidizing agents and operating parameters like temperature, activator concentration, CO2 loading and pH. The study consists of two major models: Vapor-liquid Equilibrium (VLE) model and electrochemical corrosion model. The electrolyte-NRTL equilibrium model was used for determination of concentration of chemical species in the bulk solution. The results of speciation were subsequently used for producing polarization curves and predicting the rate of corrosion occurring at the surface of metal. An increase in concentration of activator, increases the rate of corrosion of carbon steel in mixtures of activated DEA.

A naphthalimide-based fluorescent probe for the highly sensitive and selective detection of nerve agent mimic DCP in solution and vapor phase

Although human beings enjoy a relatively peaceful atmosphere, chemical terrorist attacks are still a public safety emergency, and the ability to rapidly and precisely detect chemical warfare agents (CWAs) presents a major challenge. In this study, we have developed a simple fluorescent probe based on naphthalimide that displays high selectivity and sensitivity for the nerve agent mimic diethyl chlorophosphate (DCP) in DMF solution. This probe, which is weakly fluorescent because of the PET character of the piperazine moiety, displays significant green emission in the presence of DCP. Based on the fluorescence calibration curve, the detection limit of this DCP probe was measured to be as low as 5.5 nM. Futhermore, the probe solution or filter paper can be used to selectively and sensitively detect DCP vapor, which shows the potential of its practical application.

Modeling and validation of carbon dioxide absorption in aqueous solution of piperazine plus methyldiethanolamine by PC-SAFT and E-NRTL models in a packed bed pilot plant: Study of kinetics and thermodynamics

A pilot plant with a closed cycle of the absorption/desorption process has been taken into account for the simulation of carbon dioxide (CO2) capture by piperazine (PZ) + methyldiethanolamine (MDEA) solution using Aspen Plus rate-based model with all design and operational parameters such as the hydraulic specifications of absorber and stripper as well as inlet flue gas conditions which are present in a commercial gas-fired burner for heating houses. Metal FLEXIPAC 250Y has been considered as the packing type to apply the model to the proposed correlations on Aspen Plus for calculation of flooding and pressure drop. In order to simulate the process, a new property package has been developed by electrolyte non-random two-liquid (E-NRTL) model and perturbed-chain statistical associating fluid theory (PC-SAFT) equation of state which are used for the calculation of activity and fugacity coefficients respectively. The model has been compared with some experimental data e.g. CO2 absorption efficiency and CO2 loading and demonstrated good agreement with them. (C) 2020 Institution of Chemical Engineers.

Novel piperazine-containing oligomer as flame retardant and crystallization induction additive for thermoplastics polyurethane

In flame-retarding polymer field, it is very difficult to achieve simultaneous outstanding flame retardancy and excellent mechanical properties, thus causing the serious lack of high-performance flame-retarded polymers. In this work, a novel piperazine-containing additive with phosphorus and alkynyl, named poly (2-butyne-1,4-diol piperazine bisphosphonate) (PPBPP), was designed to fabricate flame-retarding high-performance thermoplastics polyurethane (TPU). Experimental results showed that 3.0 wt% PPBPP endowed TPU with a UL-94 V-0 rating in burning test, and the melt dripping of TPU disappeared at 12.0 wt% PPBPP. More importantly, mechanical properties of flame-retarding TPU/PPBPP remarkably recovered with increasing the PPBPP, and the elongation at break for TPU containing 12 wt% PPBPP reached 812.1%, be almost equivalent to that of pure TPU, which is totally different that occurred in traditional flame-retarding TPU system. The study on mechanical recovery mechanism demonstrated that the PPBPP-induced crystallization of TPU made up for the destruction of PPBPP to hydrogen bonding in the hard segment domain of TPU and the following mechanical loss of matrix, leading to the remarkable recovery in mechanical properties of flame-retarding TPU. The study on the flameretardant mechanism illustrated that alkynyl in PPBPP underwent crosslinking process during heating, and the formed network structure joined the charring of phosphorus-nitrogen flame retardant and effectively promoted the condensed-phase flame-retardant efficiency of PPBPP and anti-melt dripping performance of TPU/PPBPP. This work proposed an efficient route for fabricating flame-retarding high-performance TPU, namely, introduction of piperazine groups into functional flame retardant compensates for the damage of additive to mechanical properties via the induced crystallization and then achieves simultaneously flame retardation and high performance of TPU.
