Agricultural By-products as Adsorbents to Reduce Bioavailability of Contaminants
Commodity Utilization Research
2010 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.
Samples of char materials were made and shipped to the collaborator, who has started doing experiments. This project will be extended for one year. The program was monitored via email.
