Abstract

The adsorption of lead (Pb) ions from an aqueous solution onto shrimp shell was evaluated in the present study. Several such important parameters influencing the adsorption of Pb (II) ions as initial pH, equilibrium time as well as different initial concentrations of Pb (II) ions was evaluated. The results indicated that the pseudosecond-order KINETIC model could describe the KINETICs of Pb adsorption by the adsorbent. With increase in Pb concentration from 100 to 1000 mgL-1, the level of Pb adsorbed by shrimp shell increased from 9 mg g-1 to 90.2 mg g-1. Increasing suspension pH from 4 to 7 enhanced the adsorption of Pb. Further increase in pH from 7 to 10 resulted in decrease in the adsorption of the metal ion. The average adsorption of Pb by the adsorbent at pHs 6 and 7 exceeded 95 percent. The Sips and Freundlich models well described the adsorption of Pb ISOTHERMS, data. Infrared spectrum analysis of adsorbent (prior to, and after adsorption of Pb) showed that the N atoms of the amine functional groups played a major role in shrimp shell for the adsorption of Pb.
