Abstract

Heavy metals are detrimental to living organisms and ecosystems because they are non-biodegradable and accumulate in the environment and food chain. The research objective was to determine the maximum contact time, pH, and the isothermal adsorption model for the adsorption of Ni2+ ions by the chitosan membrane of rice snail shells. Contact time and pH are determined by varying these variables. The Langmuir and Freundlich isothermal model was analyzed by varying the initial ion Ni2+ concentrations The results showed that the adsorption of Ni2+ ion has 120 min of maximum contact time with 72,52% Ni2+ ions that could be adsorbed, while the optimum pH at pH 5 with Ni2+ ions adsorbed by 60.96%. The isothermal adsorption model of rice snail shell chitosan membrane adsorbs ions Ni2+ following the Freundlich isothermal model with the equation y = 0.9172 x – 0.3698 and R2 = 0.9203 and the capacity adsorption was 2.343 g/L.
