Project Details
Description
Chromium(VI) (Cr(VI) is a highly toxic and mobile pollutant. Cr(VI) is mainly found in connection to pollution from tanneries, electroplating and wood preservating activities. Cr(VI) can be reduced to Cr(III) which is less toxic and mobile by addition of reductants.
The objectives of this project is to evaluate through laboratory experiments the possibility of
1) to reduce Cr(VI) in pumped groundwater in on-site filters containing metallic iron.
2)to reduce the Cr(VI) in soils by adding metallic iron or other reductant
In 1999 the experiments made for optimizing the on-site filters was finilized and reported. Experiments with three different chromium polluted soils using zero-valent iron and ferro sulfate has been carried out. The experiements showed that the reduction of chromate in soils might be possible using ferro sulfate, but the use of zero-valent iron was not feasible. The reporting of the soil experiments was finalized as well
