Equilibrium and kinetic studies of Pb (II) biosorption from aqueous solution using shrimp peel

Journal Title: International Research Journal of Applied and Basic Sciences - Year 2015, Vol 9, Issue 11

Abstract

Heavy metals are non-degradable in the environment and can be harmful to a variety of living species. So, the removal of these metals from waters and wastewaters is important in terms of protection of public health and environment. Biosorption is one of methods for removing these metals. In this study, biosorption of lead ion from the aqueous solution using shrimp peel species of Vanami has been investigated. For this purpose, effect of effective parameters such as pH, concentration of adsorbent, contact time for adsorbent and solution, initial concentration of metal ion and agitation speed on the adsorption process were studied. The best efficiency for adsorption of Pb ions by shrimp peel is determined 98 % obtaining at temperature, pH, contact time, the concentration of adsorbent, initial concentration of Pb ions and agitation speed 30oC, 6, 130 min, 5 g/L, 60 mg/L and 200 rpm, respectively. To study the equilibrium behavior of adsorbents, several equations such as Longmuir, Frendlich, Temkin, were used. Also, pseudo-first order, pseudo-second order kinematic models, particle penetration, liquid film penetration, Elovich and Ritchie second-order models were used for consideration of kinetic behaviors of experimental data.
