SORPTION OF CHROMIUM SPECIES ON SOIL
The adsorption of Cr(VI) and Cr(III) by sand, sandy soil and sandy loam has been studied in batch and column experiments with "51"Cr as an analytical tracer. Increasing organic matter of soil increased with sorption of both species, as well as the reduction of Cr(VI) to Cr(III). Soluble organic matter leached out of the soil at pH 6 and pH 8, which reduced the Kd of Cr(III). Batch and column experiments gave very different results.
