Biodegradability of chlorophenols and mixtures of chlorophenols in seawater
Ecotoxicology and Environmental Safety, 1989 Laboratory studies using chemical concentrations comparable to those found in nature have provided considerable knowledge of microbial transformations in nature. Although the number of studies performed is increasing rapidly, the effects of low substrate levels on growth, enzyme induction, enzyme activity, and the use of mixtures of substrates have not

Bacterial degradation of chlorophenols and their derivatives [PDF]
Microbial Cell Factories, 2014 Chlorophenols (CPs) and their derivatives are persistent environmental pollutants which are used in the manufacture of dyes, drugs, pesticides and other industrial products. CPs, which include monochlorophenols, polychlorophenols, chloronitrophenols, chloroaminophenols and chloromethylphenols, are highly toxic to living beings due to their carcinogenic,

Use of Low-cost Adsorbents to Chlorophenols and Organic Matter Removal of Petrochemical Wastewater
Orbital: The Electronic Journal of Chemistry, 2013 The removal of 2,4 diclorophenol (2,4-DCF) and 2,4,6 trichlorophenol (2,4,6 TCF) present in petrochemical wastewater was evaluated using low-cost adsorbents, such as chitin, chitosan and coconut shells.

Self-assembly of chlorophenols in water [PDF]
Proceedings of the National Academy of Sciences, 1999 In saturated solutions of some di- and trichlorophenols, structures with complex morphologies, consisting of thin, transparent sheets often coiling into helices and ultimately twisting into filaments, were observed under the optical microscope. Freeze-fracture electron microscopy, x-ray diffraction, phase diagrams, and molecular modeling were performed

Application of Subcritical Water to Dechlorinate Polyvinyl Chloride Electric Wires
Energies, 2018 Polyvinyl chloride (PVC) electric wires were subjected to dechlorination in subcritical water at three different temperatures in a high-pressure reactor. About 2.09, 73.08, and 95.96 wt % of chlorine in PVC wires was removed during dechlorination at 200 &
