Article Preview

Ferric salt modified sands were prepared with quartz sand as a carrier and ferric salt coating by the two methods of repeat high-temperature process and repeat alkaline deposition process. The specific surface area of two ferric salt modified sands were detected, and their Pb2+ adsorption capability in different conditions were also described in this paper. The results showed that the specific surface area of ferric chloride and ferric nitrate modified sand was 2.468m2/g and 4.247m2/g respectively, which was 6.910 and 12.612 times more than that of raw quartz sand. In the neutral pH condition, the removal efficiency of Pb2+ by raw quartz sands was approximately 37%, in contrast, the removal efficiency reached 85% by ferric nitrate modified sand and over 90% by ferric chloride modified sand, and it was much higher than that of raw quartz sand.
