removal of arsenic. The effects of the physicochemical parameters; reaction time, initial arsenic concentration, pH and ion exchange resin amount on arsenic sorption were investigated. The optimum resin amounts were found to be 60 mg for Lewatit Monoplus M600 and Lewatit Sybron Ionac SR7 whereas it was 40 mg for Lewatit FO36 and Selion ASRFG3300.
