Photocatalytic Degradation of 4-Chlorophenol. 2. The 4-Chlorocatechol Pathway
The TiO2-mediated photocatalytic degradation of 4-chlorocatechol is studied as a branch of the degradation of 4-chlorophenol. In addition to some basic kinetic studies, the identities of many of the cyclic and acyclic intermediates, verified in most cases with authentic samples, are reported. From 4-chlorocatechol, the major product is hydroxylation to form 5-chloro-1,2,4-benzenetriol. A small ...
متن کاملApplication of Azolla for 2-Chlorophenol and 4-Chrorophenol Removal from Aqueous Solutions
Background and purpose: The 2-chlorophenol (2-CP) and 4-chlorophenol (4-CP) are phenolic compounds which may have adverse effects on human and environment. Therefore, removing these compounds from water and wastewater is necessary. This study aims to analyze 2-CP and 4-CP removal by using Azolla filiculoides biomass. Materials & Methods: Azolla biomass was sun dried, crushed and sieved to parti...
متن کاملDerivatization of 2-chlorophenol with 4-amino-anti-pyrine: a novel method for improving the selectivity of molecularly imprinted solid phase extraction of 2-chlorophenol from water.
Molecularly imprinted polymer (MIP) may not selectively recognize small template of limited number of functional groups, such as 2-chlorophenol (2-CP). In this work, a novel method was proposed to improve the recognition ability of the molecularly imprinted solid phase extraction (MISPE) of 2-CP from environmental waters. This was achieved by derivatization of 2-CP with 4-amino-anti-pyrine (4-A...
متن کاملOxidative Degradation of 2-chlorophenol by Persulfate
The degradation of 2-chlorophenol (2-CP) by persulfate was investigated. The kinetics of persulfate oxidation of 2-chlorophenol in aqueous solutions at various pH, oxidant concentration, temperature, Fe2+ and Cu2+ ions content was studied. Maximum of 2-CP degradation occurred at pH 8. The oxidation rate of 2-CP increased with increasing the persulfate molar excess. The degradation process was s...
متن کاملOral carcinogenicity and toxicity of 2-amino-4-chlorophenol in rats.
OBJECTIVES This study was carried out to clarify the subchronic and chronic toxicity, and carcinogenicity of 2-amino-4-chlorophenol(ACP). METHODS Carcinogenicity, and chronic and subchronic toxicity of ACP were examined by feeding 10 rats of both sexes ACP-containing diet at a dose level of 0 (control), 512, 1,280, 3,200, 8,000 or 20,000 ppm (w/w) for 13 wk and 50 rats of both sexes at a dose...
