KINETICS AND EQUILIBRIUM STUDIES OF ADSORPTION OF Pb AND Cu ON LOCAL CLAY SOIL SAMPLE

Abdullahi Moyosore, Kamaldeen Abdullahi

Abstract


Kinetic studies of adsorption of Pb(II) and Cu(II) ions on local clays soil from Dan-Iyau Daddara in Jibiya Local Government Area of Katsina State have been studied using batch experimental method. The optimum parameters deployed for the equilibrium study are time of contact (50mins for both metal ions), adsorbent mass (0.6g for Pb, 0.8g for Cu) and adsorbate dosage (15mg/L for Pb, 20mg/L for Cu). The experimental data were correlated with adsorption Isotherm  and kinetic equations using linear regression analysis. The plots of the amount of adsorbate adsorbed against equilibrium concentration or mass of dosage of clay or time showed two distinct segments; a straight line plot at low concentrations followed by a plateau portion at high concentration were observed. The adsorption isotherm data were adequately fitted with both Langmuir and Freundlich equations. The result of the adsorption kinetics reveals that the pseudo-second order model, appeared to be the best-fitting model for the sorption of Pb(II) and Cu(II). The investigations show that Daddara, Dan-Iyau clay could be an effective low-cost adsorbent for removal of Pb and Cu from waste water and industrial effluents.
