Popis: Metapenaeus monoceros shell used for the removal of reactive red 2 from an aqueous solution was studied by batch biosorption system. The maximum dye uptake capacity was examined at biosorbent dosage, different pH, contact time and initial dye concentration. From the study the maximum dye uptake capacity was obtained as 166 mg/g at an optimal condition of 0.1 g/L of biosorbent dosage, pH value of 2 and initial dye concentration of 100 mg/L. When compared to the Langmuir isotherm model, the equilibrium data were fitted well with the Freundlich isotherm model. The kinetic data were fitted well with the pseudo second order rate equation when compared to the pseudo first order rate equation. The biosorbent characteristics were observed by SEM and FTIR analyses.
