| description | Cadmium (Cd) is one of the heavy metals which contaminate the environment including water, air, and soil. At low concentrations, Cd produces adverse effects in
aquatic organisms. An effort to reduce the level of Cd was conducted by removing the metal with chitosan. The aim of this study was to study the adsorption of Cd by using chitosan isolated from the shrimp Penaeus sp. as a function of stirring duration and chitosan concentration in aqueous solution. In this study, chitin was isolated by using NaOH 3% and HCl 1.25 N, adding NaOH 50% for the transformation of chitin to chitosan. For the adsorption test, chitosan was added to Cd solutions at concentrations of 0.2, 0.4, or 0.6 g per 10 ml Cd(NO3)2, stirring the solution for 5, 10, or 15 min,
respectively. The results showed that the yield of isolated chitosan was 56% of crude prawn shell. The optimum concentration of chitosan was 0.6 g/10 ml with a stirring duration 10 min reducing Cd concentration by 91.7%. |
