Abstract

The removal of toxic metals like lead (Pb) is very vital in keeping its hazardous effects in view. The study examined the prospect of using Albizia lebbeck (Indian Siris) as a low-cost adsorbent for the removal of lead metal from contaminated waters. A batch experiment was conducted to examine the influence of pH, temperature, initial metal ion concentration; adsorbent dose and contact time, mixing speed on the bio-adsorption of Lead (Pb) by Albizia lebbeck (seed). Langmuir and Freundlich’s isotherms were used to describe the adsorption of organic and inorganic compounds on a wide variety of adsorbents at equilibrium. The heavy metal Analysis was characterized by Spectroscopy (AAS), amount of removal material by adsorbents through series of batch investigations while the amount adsorbed was calculated by the difference of initial concentrations of the metal ion in solution (mg/L) and final concentrations of metal ion solution (mg/L). The result showed that the sorption capacity increased with an increase in the initial concentration of adsorbate and it was pH-dependent. The rate of metal-binding with biomass is more predominant during the initial stages, which gradually decreases and remains almost constant after equilibrium time. Adsorbent gets involved in metal complexation at active adsorption sites as early as the adsorbent is introduced into the system.
