Abstract
Water pollution from heavy metal in the wastewater is one of the most serious concerns of the world. It can be harmful to the environment and humans, so this problem needs to be overcome. In the present study, we examine about biosorption process, isotherm, and kinetic model for the removal of Lead (Pb), Cadmium (Cd), and Copper (Cu) by lorjuk shell powder (Solen vagina). Lorjuk is one of the leading marine commodities in East Java, which generally only consumes meat, while shells have the potential to become waste. The characteristics of the lorjuk shell powder (Solen vagina) used in the study were gray color with a size of 100 mesh that contains water content, protein, minerals, and chitin. Most of the minerals are calcium and its functional groups contain C = O which is important in metal binding. The greater the initial levels of Pb2+, Cd2+, and Cu2+ cause an increasing adsorption capacity, while the increasing biosorbent mass causes the adsorption capacity to decrease. Based on the percentage of efficiency, the optimum condition of parameters in this study were 100 mg/L (initial metal concentration); 1.5 grams of Pb2+ and Cd2+; 2 grams for Cu2+(biosorbent mass); 20 minutes for Pb2+, 60 minutes for Cd2+, and 120 minutes for Cu2+ (contact time) with a percentage more than 90%. This is due to the inverse relationship between the adsorption capacity and the biosorbent mass of the equation. Mulivariate ANOVA and Kruskal Wallis statistical analysis were showed a significant difference in the biosorption process between parameters (initial metal concentration, biosorbent mass, and contact time) for Pb2+, Cd2+, and Cu2+ metals respectively.
