“…The formation of -COOH functionalities during cross-linking of diamine and trimesoyl chloride is the cause of development of negative charge on membrane surface [37]. The electrostatic interaction between membrane and ions in the solution has a major role to play for the charged membrane.…”

A B S T R A C TThe thin-film composite membrane is aptly named as thin polyamide layer on the asymmetric polysulfone membrane. These membranes have salt rejection abilities, and the order is NaCl > CaCl 2 . Addition of NaCl increases (17.39% for 500 mg/L for Memb-II), whereas CaCl 2 decreases (5.94% for 500 mg/L for Memb-II) atrazine separation. Surfactant-mediated filtrations showed mixed results. Sodium lauryl sulfate (SLS) results better atrazine separation. SLS (200 mg/L) increases 29.72% separation for Memb-II. Contrary to SLS, Cetyl trimethyl ammonium bromide shows little negative influence (10.91%) and for Triton-X-100 (19.3%) it shows more deterioration effect for the same membrane, keeping the same concentration.

2015) Effect of operating parameters on 2-chlorophenol removal from wastewaters by a low-pressure reverse osmosis system, Desalination and Water Treatment, 55:1, 114-124, A B S T R A C TIn this study, the performance of a commercial low-pressure reverse osmosis membrane system (TW30-1812-100) was evaluated for 2-chlorophenol removal from wastewaters. The influence of various operational conditions and system specifications such as feed pressure, feed flow rate, pH, and concentration on 2-chlorophenol rejection was investigated. The results showed that at optimum conditions (200 ppm feed concentration, 408.1 kPa feed pressure, pH 10, and 1.953 × 10 −5 m 3 /s feed flow rate) 79% rejection was attainable. In addition, it was found that at the feed pH was the most effective parameter on 2-chlorophenol rejection. The rejection was increased with feed pH. An increase of feed flow rate had a positive effect on 2-chlorophenol rejection. The study of the influence of feed pressure showed a maximum critical pressure for rejection. However, the study of feed concentration on 2-chlorophenol rejection did not show a clear trend.

“…Chlorophenols have been used extensively as pesticides, dyes, petrochemicals, paints, perfumes, and pharmaceuticals (Kim et al 2006;Ranjit et al 2008;Yogesh et al 2008). However, these compounds are probable carcinogens and exhibit considerable water solubility and high toxicity.…”

This study investigated the encapsulation and photocatalysis of chlorophenol compounds in water using porphyrin-(polystyrene-b-2-dimethylaminoethyl acrylate) star polymer. The chloride ions generated during photocatalytic process were identified and quantified. 2,4,6-Trichlorophenol, pentachlorophenol, and 2,4-dichlorophenol were satisfactorily decomposed in the photoreactor using porphyrin-(polystyrene-b-2-dimethylaminoethyl acrylate) star polymer, with removal efficiencies of 2,454, 498, and 760 mg/ g of porphyrin-(polystyrene-b-2-dimethylaminoethyl acrylate) star polymer. The half-life times reached around 30 min, with the exception of that for 2,4-dichlorophenol. The star polymer-impregnated porphyrin is a promising photocatalyst for the removal of chlorophenols.
