Sequential UV-biological degradation of chlorophenols.
The sequential UV-biological degradation of a mixture of 4-chlorophenol (CP), 2,4-dichlorophenol (DCP), 2,4,6-trichlorophenol (TCP), and pentachlorophenol (PCP) was first tested with each pollutant supplied at an initial concentration of 50 mg l(-1). Under these conditions, the chlorophenols were photodegraded in the following order of removal rate: PCP>TCP>DCP>CP with only CP and DCP remaining...
متن کاملBacterial degradation of chlorophenols and their derivatives
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, mutagenic and cytotoxic properties. Sever...
متن کاملDevelopment and Characterization of Nanocomposite Membranes based on Chitosan, Polystyrene and Montmorillonite for Pervaporation Separation of Phenol and Chlorophenols from Water
The novel nanocomposite membranes were successfully prepared by the incorporation of different concentrations (5, 10, and 15 wt%) of montmorillonite (MMT) as a nanoadditive into a blend of chitosan/polystyrene (CS/PS) at a ratio of 3:1 on the basis of solution-casting method and they were subsequently used for the separation of phenol, p-chlorophenol, and 2,4-dichlorophenol from water through p...
متن کاملElectrophoretic separation of chlorophenols on silica nanospheres-coated poly(dimethylsiloxane) microchip using a Nafion/graphene-modified carbon electrode for detection.
In the present work, the micellar electrophoretic separation of five chlorophenols (CPs) on a functionalized poly(dimethylsiloxane) (PDMS) microchip with amperometric detection was performed. In order to achieve high resolution by controlling the electroosmotic flow (EOF) as well as signal detection by suppressing analytes adsorption, the microchannel was functionalized by poly(diallyldimethyla...
متن کاملSelf-assembly of chlorophenols in water.
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 to elucidate the observed phenomena. Here,...
