Abstract: In this research work, Low-cost adsorbent was prepared from Camellia sinensis,
physicochemical characteristics and the effective removal of Lead and Zinc from an aqueous
phase were evaluated.The Camellia sinensis adsorbent precursor was characterized in terms
of adsorbent dose, initial concentration and contact time. Aqueous phase adsorption studies
were carried out under kinetic studies of pseudo first order, pseudo second order kinetics and
the residue concentration of Lead and Zinc were determined with the aid of a spectrometer.
From the result of this studies, initial concentration has little effect in the removal, at lower
concentration, the % removal is higher with just slight difference, in this study, the optimum
initial concentration was 0.1 M. At optimal conditions, Lead and Zinc uptake increases with
increase in biosorbent dose, in this study the optimum dosage was 2 g. The removal of Lead
and Zinc was more than 90% in 10, 20, 30 and 40 minutes of contact time thus, presenting
Camellia sinensis as a suitable adsorbent that can be used for effective removal of high Lead
and Zinc concentration in water as shown by the adsorption kinetic studies.
