Location: Commodity Utilization Research2012 Annual Report
1a. Objectives (from AD-416):
This project has an objective to study how ARS-manufactured carbons can be used to adsorb heavy metals and chlorinated organics in contaminated sediments. This adsorption may cause the contaminants to be less available to biota.
1b. Approach (from AD-416):
ARS will test ARS-manufactured activated carbons on surrogate wastewaters. The "best" carbons will be forwarded to the collaborator at University of Maryland. The collaborator will test the activated carbons in a sediment matrix for adsorption capabilities and for reduced contaminant bioavailability.
3. Progress Report:
Samples of activated chars shipped to collaborator were tested and it was preliminary concluded that the char made by USDA-ARS out-performed all the other char materials tested as it pertained to removal of mercury from water.
