The existence of waste metal ion Cd2+ and Pb2+ collectively in an aquatic environment is polluters that challenging to avoid, therefore needed adsorbent which can selectively decline the level of pollution. This study utilizes crosslinked chitosan as an adsorbent to select and decline the ions of Cd2+ and Pb2+. The study included crosslinked chitosan with sodium tripophosphate, followed by interaction of adsorbent with each metal ion using batch method such as determination of optimum pH, optimum concentration of tripolyphosphate and adsorbent competition test on adsorption of Cd2+ and Pb2+ ions. The optimum pH result obtained optimum pH of Cd2+ and Pb2+ ions using chitosan-tripolyphosphate (KSP) adsorbent which optimum at pH 6 for Cd2+ and pH 3 for Pb2+ ions. Optimum concentration of tripolyphosphate chitosan 2% (b / v). It was concluded that KSP adsorbent was selective against Pb2+ ion in the competition test. © 2018 Author(s).
