    Abstract

    The reduction of toxic metal, especially Cr6+, could be done by ion exchange resin. The substitution of Cr6+ ion with other non-toxic ion contained in the resin will reduce the amount of toxic chromium to the permitted level. In this study ion exchange was done using Dowex SBR-P (Styrene-DVB) anion resin. Experiments were done using potassium dichromate (K2Cr2O7) as source of Cr6+ ion. This compound was diluted in water inside a beaker glass. Then a desired amount of resin were added and stirred at until a desired time reached. The result was analyzed by spectrophotometric method using 1-5 diphenylcarbazide (DPC) as an indicator. Results shows the highest adsorption was 40.64%, reached at stirring speed of 190 rpm, for 60 minutes and resin weight 25 gram with the amount of potassium dichromate 3.3 gram. Keywords: chromium metal, ion exchange resin
