Use of Biochar to Remediate Arsenic and Antimony Contaminated Soils.

Due to its high adsorption capacity, biochar has high potential to remediate contaminated soils. In this study, biochar was applied to a soil containing elevated concentrations of arsenic (As) and antimony (Sb) to test if it would reduce plant availability. Results indicate that As bioavailability was significantly reduced, while effects on Sb bioavailability were not significant.
