摘要：
The parameters influencing the extraction efficiency of total water-soluble chromium and chromium(VI) in clay, peat and sandy soils were investigated. Water and a KH2 PO4 solution (0.015 mol dm(-3)) were used as extractants. Samples were ultrasonicated or shaken in classical shakers. Variations of solution volume-to-soil weight ratio, and of shaking time were studied in order to develop the optimal extraction procedure for the determination of total water-soluble chromium and chromium(VI). Soil samples treated with tannery waste continuously for 17 years and soils freshly contaminated with the same waste were studied.
