In the present study, a Schiff's base polymer (SBP) has been synthesized by the condensation of trifluoroacetylacetone and amino-polystyrene copolymer resin. After the characterization of synthesized polymer by FT-IR spectroscopy, thermal and elemental analyses, the removal of 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP) along with phenol is optimized using response surface methodology. Eighteen runs design were performed with different levels of variables in order to optimize sorption parameters such as pH, concentration of adsorbate, agitation time and amount of polymeric resin SBP. Maximum Langmuir sorption capacity obtained was 110.7, 125.3 and 195.4 mg g(-1), for phenol, 2-CP and 2,4-DCP, respectively. Recovery of adsorbed phenol, 2-CP and 2,4-DCP was checked by different solvents and was found to be quantitative ( 99%) with methanol. The model was validated by performing sorption experiments at optimum conditions. Kinetic and isotherm studies of all three analytes on SBP are also discussed.
