Abstract

The effect of pomelo peel on the adsorption of organic dye rhodamine B (RB) was explored through a series of experiments. The influence of factors including pH value, initial concentration of RB, dosage of pomelo peel, and temperature upon adsorption of RB in aqueous solution was studied. The results of experiments indicate that the optimal conditions for pomelo peel as the biologic material to absorb RB include 0.6 g pomelo peel, 20 mg/L RB, initial solution pH value of 3 and reaction time of 20 minutes, where the removal (adsorption rate) reaches 60.9%. The second-order dynamic adsorption model well describes the adsorption dynamics process of RB by pomelo peel. As the concentration of RB increases, the absorption capacity rises.
