英文摘要Combined batch sorption and in situ X-ray absorption fine structure (XAFS) provide direct assessment of the mechanisms for Pb(II) sorption at the soil-water interface under different pH conditions. The XAFS data indicated that the innersphere Pb sorption complex with ionic character (Pb(4) (OH)(4)(4+)) dominated the Pb surface speciation, and the outer-sphere Pb sorption complex and the precipitation of calcium carbonate containing Pb(PbCaCO(3)) were also involved in the adsorption samples. Coordination number and radial distance of the first-shell Pb-O decreased from 0. 172 7 to 0. 166 6 nm and the percentage of inner-sphere complexes increased when the initial pH changed from 6. 0 to 8. 5, indicating that the mechanism of Pb(II) sorption by the soil was pH-dependent.
