“…In addition, requirement for specific redox conditions, for anaerobic degradation [9] and accumulation of more toxic chlorinated intermediates [4] following the incomplete aerobic degradation processes restrict the field application of biological systems for remediation of water contaminated with PCP. Advanced oxidation processes have been reported for the effective oxidation of PCP [10]. However, such processes are expensive, non-selective and attack chlorinated and non-chlorinated compounds with equal potency.…”

“…The USEPA set an upper permissible limit of 0.5 mg/L for chlorophenols in public water supplies in 1987 (Chang et al 2015). The current drinking water guideline values in the US for 2-CP and 2,4-DCP are 0.1 and 0.5 μg/L, respectively (Pera-Titus et al 2004). The EU has set target limits in drinking water of 0.5 and 0.1 μg/L for total content of chlorophenols and individual ones, respectively (Peng et al 2007;Elci et al 2011).…”

Sorption of 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP), and 2,4,6-trichlorophenol (2,4,6-TCP) on a range of dealuminated zeolites were investigated to understand the mechanism of their sorption on microporous minerals, while the influence of common metal cations, solution pH, and humic acid was also studied. Sorption of chlorophenols was found to increase with the hydrophobicity of the sorbates and that of the microporous minerals, indicating the important role of hydrophobic interactions, while sorption was also stronger in the micropores of narrower sizes because of greater enhancement of the dispersion interactions. The presence of metal cations could enhance chlorophenol sorption due to the additional electrostatic attraction between metal cations exchanged into the mineral micropores and the chlorophenolates, and this effect was apparent on the mineral sorbent with a high density of surface cations (2.62 sites/nm 2 ) in its micropores. Under circum-neutral or acidic conditions, neutral chlorophenol molecules adsorbed into the hydrophobic micropores through displacing the Bloosely bound^water molecules, while their sorption was negligible under moderately alkaline conditions due to electrostatic repulsion between the negatively charged zeolite framework and anionic chlorophenolates. The influence of humic acid on sorption of chlorophenols on dealuminated Y zeolites suggests that its molecules did not block the micropores but created a secondary sorption sites by forming a Bcoating layer^on the external surface of the zeolites. These mechanistic insights could help better understand the interactions of ionizable chlorophenols and metal cations in mineral micropores and guide the selection and design of reusable microporous mineral sorbents for sorptive removal of chlorophenols from aqueous stream.

“…A wide variety of advanced oxidation processes (AOPs) have been reported for the removal of pentachlorophenol which have been reviewed by Pera-Titus et al [4]. Electrochemical reductive dechlorination and electrooxidation by in situ generated hydroxyl radicals are also reported [5][6][7].…”
