Abstract

Methyl Orange Adsorption was studied using Durio zibhethinus Murr seeds. Examined parameters are pH of solution, initial dye concentration, biosorbent mass, stirring speed, contact time, and temperature of heating. The optimum absorption capacity of Methyl Orange is obtained at a concentration of 80 mg/L is 6.352 mg/g at pH=2, 0.05 g biosorbent dose, stirring speed 200 rpm, contact time of 40 minutes and temperature of 50°C. Appropriate adsorption isotherm models namely Freundlich isotherm models with correlation coefficient 0.973.
