Elimination of Lead Ions from Aqueous Environment by Waste Tires Rubber

Abstract

The investigation goes through paper to taking away of lead ions from aqueous medium by waste tire rubber granules(WTRG). The effect of various operational parameters like period of time, original metal concentration, size of adsorbent particles, adsorbent dose, and PH of medium on the adsorption ability of WTRG was evaluated. The kinetic of the adsorption process was relatively fast with approximately one hour of equilibrium time. A tiny adsorbent particle size (0.04 mm), PH medium (5-6) preferential the adsorption process. Data of isotherm studies exposed that adsorption of Pb(II) was well expressed by the Langmuir isotherm formula (R2=0.993). The study demonstrated the ability of WTRG to remove lead from aqueous environment as a cheap and available material. The use of WTRG exhibited the safe disposal of solid waste. Hence its with double benefit for environment.
