Location: Commodity Utilization Research2009 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
Activated carbons were produced from turkey and chicken litter. The unwashed activated carbons were tested for their ability to soak up cadmium, lead, mercury, zinc, and copper. The materials will be transferred to the collaborator for additional testing. The progress was monitored via periodic email and phone conversations.
