Bi25FeO40/g-C3N4 composites were synthesized for dechlorination of 2-chlorophenol (2-CP). The characteristic the obtained products was studied using X-ray diffraction (XRD), (FESEM) scanning electron microscopy, UV-vis reflectance. effects g-C3N4 content, photocatalyst dosage, solution pH, H2O2 on efficiency investigated, in addition to reusability nanocomposites. results showed that increasing...

For several years, our laboratory has isolated numerous bacterial strains from soils and wastewater contaminated with toxic compounds in order to find useful bacteria that can degrade phenolic compounds such as phenol, chlorophenol, and nitrophenol. By enrichment, many phenolic compound-degrading bacteria have been isolated (Bae et al., 1996a, b; Baek et al., 2001; Yoon et al., 1999, 2000). Fur...

A defined mixed culture, consisting of an Arthrobacter sp. and a Micrococcus sp. and able to grow with 4-chloroacetophenone as a sole source of carbon and energy, was isolated. 4-Chlorophenyl acetate, 4-chlorophenol, and 4-chlorocatechol were identified as metabolites through comparison of retention times and UV spectra with those of standard substances. The proposed pathway was further confirm...

Aqueous-phase edsorption equilibrium and kinetic mechanism of phenol, 3-chlorophenol rnd o-cresol onto Norit Granular Activaied Caibon (NAC 1240) were studied in a batch system at temperature of 30 oC, agitation speed of 120 rpm, initial phenol concentrations of 25-200 mg/t. The elfects of initid phenol concentration and time of adsorption on phenol adsorption process were lnvestigated. The ads...

In this paper, we are interested in a mechanistic model describing the anaerobic mineralization of chlorophenol three-step food web. The is six-dimensional system ordinary differential equations. our study, take into account phenol and hydrogen input concentrations as well maintenance terms. Moreover, consider case large class growth rates, instead specific kinetics. general case, recent study ...
