A mechanistic model describing the anaerobic mineralization of chlorophenol in a three-step food-web is investigated. The six-dimensional system ordinary differential equations. In our study, phenol and hydrogen inflowing concentrations are taken into account as well maintenance terms. case large class growth kinetics considered, instead specific kinetics. We show t...

The general purpose of this study is to optimise the removal of precursors of taste and odour compounds, especially 2,4,6-chlorophenol, at a water treatment plant. Nowadays, there are frequently problems of taste and odour in drinking water due to the presence of various types of compounds. Some of these are already present in the resource but o thers are generated during the chlorination stage...

in this study, magnetic nanoparticles (γ-fe2o3) were used for the degradation of 2-chlorophenol (cp) from wastewater. the size of these magnetic nanoparticles was measured using xrd and found to be about

Despite the wide application of nanoscale zero valent iron (nZVI) for the treatment of a plethora of pollutants through reductive reactions, reactivity evaluation of nZVI towards dehalogenation has not been standardized. In this light, it was desired to develop a simple colorimetric assay, for versatile laboratory application, using merely a spectrophotometer for color intensity determination. ...

The biodegradation kinetics of 4-chlorophenol (4-CP) and phenol microbial growth Pseudomonas putida (P. putida) cells were estimated in batch biofilm reactors. kinetic parameters on determined using the Haldane formula. maximum specific rate P. phenol, half-saturation constant self-inhibition 0.512 h−1, 78.38 mg/L 228.5 mg/L, respectively. yield (YP) was 0.618 mg phenol/mg cell. experimental re...

In order to assess the applicability of using microelectrodes as a tool for inhibition tests, temporal and spatial inhibitory effects of 2-chlorophenol (2-CP) on O(2) respiration and nitrification activities in municipal wastewater biofilms were investigated using microelectrodes for O(2) and NH(4)(+). The time-course microelectrode measurements demonstrated that 2-CP inhibited O(2) respiration...

The antibacterial activity of pentachlorophenol and 35 of its known or possible metabolites against 30 different species of bacteria was tested. In comparison with pentachlorophenol, no increase of inhibitory activity was found for any of the chlorinated anisoles tested (except for pentachloroanisole against Streptomyces spp.), 2-chlorophenol, 2,6-dichlorophenol, 2,3,6- and 2,4,6-trichloropheno...
