Abstract

The presence of toxic metals like lead, mercury, chromium, arsenic, etc. in water is major problem these days. This investigation involves the removal of lead from water by batch adsorption technique using α- alumina (A12O3) as adsorbent. Percentage adsorption was determined for alumina-lead solution system as a function of pH, temperature, contact time and adsorbate dose. The known quantities of lead in solutions have been adsorbed on α-alumina and the concentration of lead in the solution after adsorption was determined by atomic absorption spectrophotometer. Maximum adsorption of lead was observed at pH 10, temp.15°C, 30 minutes and low adsorbate dose. Adsorption data has been interpreted in terms of Freundlich equation. The results suggest that α-alumina is effective adsorbent for lead removal.

Key words: Toxic metals; Adsorbent; α-Alumina
