Results of in situ UV–vis spectroelectrochemical studies of the electropolymerization of o-phenylenediamine (OPD), m-toluidine (MT) and the copolymerization of OPD with MT are reported. Electropolymerization was performed in aqueous acidic medium at a constant potential of ESCE = 1.0 V at an in...

Electroactive copolymers of m-toluidine (MT) and o-phenylenediamine (OPD) were prepared electrochemically in aqueous sulfuric acid by potential cycling and characterized with cyclic voltametry, in situ conductivity measurements and FT-IR spectroscopy. The voltammograms of the copolymers exhibit ...

An integrated adsorptive technique combining an m-cresol adsorption unit, an acid retardation unit and an m-toluidine adsorption unit in sequence was designed to recover m-cresol and m-toluidine from highly acidic and salty m-cresol manufacturing wastewater. In the first column packed with hyper...

HypothesisPorous spheres of the conducting polymer polyaniline (PANI) and its derivatives are promising materials for use as functional encapsulants for payload delivery and catalyst supports. Stable water-in-oil-in water (W/O/W) double emulsions can be used to obtain this morphology, but typica...

Hydroxyl (OH) radical is proposed as an important factor in the ozonation of water. In the present study, the enhancing effect of 3-chlorophenol on OH radical generation was mathematically evaluated using electron spin resonance (ESR)/spin-trapping technique. OH radical was trapped with a 5,5-di...

The resonance enhanced multiphoton ionization (REMPI) excitation spectrum of jet-cooled 3-chlorophenol (3-ClP) was measured in combination with time-of-flight (TOF) mass spectrometry. In the TOF mass spectrum, 3-ClP, 3-ClP dimer and 3-ClP-water cluster cations were observed. The REMPI excitation...

To investigate the enhancement of phenol on the biodegradation of 4-chlorophenol (4-cp), metabolic profiling approach was performed for the first time to analyze metabolite changes of Pseudomonas sp. cbp1-3 using single substrate (succinate, phenol, and 4-cp) and dual substrate (mixtures of phen...

Strong adsorption of pollutants on activated carbon may inhibit their diffusion to the catalyst on the surface of the adsorbent and hence reduce the whole photocatalytic process. Oxidation of the carbon surface will change the adsorption properties of the carbon; and increase the capability of c...

Photocatalytic activity of nitrogen modified TiO2 calcined at temperatures of 100–350 °C toward 3-chlorophenol (3-CP) degradation was studied. In the experiments the fluorescent UV lamp and the incandescent lamp emitting mainly Vis light were applied. The degradation efficiency was evaluated o...

Nanoscale Al particles with average diameter of about 100 nm were employed to prepare Pd/Al nanoparticles (NPs) by chemical displacement deposition. It was proved that Pd2+ acidic deposition solution was superior to its alkaline deposition solution in terms of Pd loading rate on Al NPs. The Pd/A...

A commercial multiwall carbon nanotube and its carboxylated derivate (CNTC and COOHC, respectively) was used after purification to study the competitive adsorption of phenol (P) and m-chlorophenol (CP) from 0.1 M aqueous NaCl solutions without external pH control. The adsorption takes place prac...

In the present paper, a β-cyclodextrin (β-CD) functionalized graphene modified carbon paste electrode (CD/GRs/CPE) was prepared and characterized by atomic force microscopy (AFM), Fourier transform infrared (FT-IR) and electrochemical impedance spectroscopy (EIS). The electrochemical behaviors...

BackgroundChlorophenols (CPs), suspected as endocrine disrupting chemicals, exposure during early life may contribute to body size. However, limited human data with inconsistent findings have examined the developmental effects of CPs exposure.

In present work, SnO2 nanoparticles were synthesized using simple hydrothermal process, and then a novel PbO2/SnO2 electrode was successfully fabricated using obtained SnO2 nanoparticles for electrochemical oxidation of 3-chlorophenol (3-CP). The microstructure, element distribution, crystal str...

Excess volume (VE), excess isentropic compressibility (κsE), viscosity deviation (8η) and excess Gibbs energy of activation of viscous flow (G*E) for binary mixtures of 3-chloroaniline (CA) with 1,2-dichlorobenzene (1,2-DCB), 1,3-dichlorobenzene (1,3-DCB) and 1,2,4-trichlorobenzene (1,2,4-TCB)...

Sonolysis and photolysis are compared for the transformation of chlorpropham, a systemic herbicide belonging to the carbamate group, and 3-chloroaniline, the main intermediate often observed in the degradation of chlorpropham. In both cases the ultrasonic degradation is much more efficient at 48...

Two new organic-inorganic hybrid compounds, 3-chloroanilinium nitrate (I) and 3-chloanilinium perchlorate (II), have been synthesized by an acid/base reaction at room temperature in the presence of 3-chloroaniline as an organic-structure directing agent and their structures were determined by si...
