| Abstract | Heavy metals in wastewater from various sources pose significant risks to ecosystems and humanhealth. This study investigates the effectiveness of chitosan, a biopolymer derived from seafoodwaste, in removing chromium (Cr) and copper (Cu) from domestic wastewater. The adsorptionefficiency of chitosan was evaluated based on adsorbent dosage and contact time. Chitosanwas synthesized through demineralization, deproteination, and deacetylation of seafood waste.Adsorption experiments were conducted using chitosan dosages of 2 g, 4 g, and 6 g, with contacttimes of 5, 30, and 60 minutes. The results indicate that increasing the adsorbent dosage enhancesthe removal efficiency of both Cr and Cu ions. Specifically, Cr removal improved from 34.73%at 2 g to 56.25% at 4 g and further to 78.40% at 6 g. Similarly, Cu removal efficiency increasedfrom 28.21% at 2 g to 56.41% at 4 g and reached 82.05% at 6 g. Additionally, prolonged contacttime significantly enhanced metal ion removal. Cr removal increased from 18.06% after 5 minutesto 50.00% after 30 minutes and 72.92% after 60 minutes. A similar trend was observed for Cu,with removal efficiency rising from 17.95% at 5 minutes to 55.13% at 30 minutes and 75.64% at60 minutes. These findings suggest that extended contact time provides greater opportunities foradsorption, improving the removal efficiencies of Cr and Cu ions. Overall, this study demonstratesthat chitosan is an effective adsorbent for Cr and Cu removal from wastewater, with adsorptionefficiency influenced by both adsorbent dosage and contact time. |
