Equilibrium, kinetic, and thermodynamic studies of lead

Apr 01, 2017· The adsorption of Pb(II) and Zn(II) increase from 34.72 to 62.19 mg g −1 and 29.46–49.98 mg g −1 as the initial concentration increases from 150 to 350 mg L −1. Increase in the adsorbent dosage from 0.2 to 1 g resulted in gradual increase in the equilibrium adsorption capacity (mg g −1 ) of POMEAC from 17.23 to 22.46 fro Pb(II) and 15
