Patent DE-19828665-A1 (DE)
Inventor: JAMES BRUCE R
IPC: A62D3/00
Filed: 1998-06-26
Abstract: The concentration of potentially toxic hexavalent chromium Cr(VI), in chromium-bearing soils/materials existing in the form of soils, sludges, sediments, fill, industrial wastes, or other materials is decreased by applying and mixing a single reducing agent, ascorbic acid, to effect chemical reduction of Cr(VI) to a less toxic valence state. Ascorbic acid is added at ambient temperature in aqueous solution or slurry form and mixed with Cr(VI)-bearing soils/materials in amounts based on test results or representative samples of the material to be treated. Ascorbic acid may also be added in a dry form if sufficient moisture is present in the soils/materials to allow for dissolution of the ascorbic acid and reaction with the Cr(VI) in the material. The percentage reduction of the Cr(VI) concentration is greater and is achieved more rapidly than previously reported using other organic chemical reducing agents.
