The sorption data obtained were evaluated using well‐known kinetic and adsorption isotherm models. The kinetic data obtained for the two resins fitted well to the pseudo‐second‐order model and the Langmuir isotherm. Besides, it was observed that temperature influenced slightly the sorption properties of the ion exchange resins synthesized in this study and commercially available ion exchange resin Amberlite IRA‐400.</bold> </p> </sec> <sec id="jctb4320-sec-0003" sec-type="section"> <title>CONCLUSIONS</title> <p id="jctb4320-para-0003"> <bold>The synthetic resins showed a better sorption performance than a commercially available ion exchange resin. The P(ClVBTA) and P(ClAPTA) resins exhibited greater and faster sorption than Amberlite IRA‐400. Sorption capacities of these ion exchangers were found to be in the order P(ClAPTA) > P(ClVBTA) > Amberlite IRA‐400. © 2014 Society of Chemical Industry.</bold> </p> </sec> </abstract>
