In Situ Immobilization of Heavy Metals in Apatite Mineral Formulations

Abstract

The sorption and selectivity of aqueous Pb, Cd, and Zn onto a mineral apatite from North Carolina were investigated in relation to a wide range of pH. The heavy metals were applied as single species and multiple species. The sorption of aqueous Pb was primarily through a process of the dissolution of apatite followed by the precipitation of variable pyromorphite-type minerals. Hydrocerussite Pb3(CO3)2(OH)2 or Pb(OH)2 . 2PbCO3 and lead oxide fluoride (Pb2OF2) formed only under extremely alkaline condition.
