Research Project: Agricultural By-products as Adsorbents to Reduce Bioavailability of Contaminants

Location: Commodity Utilization Research

2008 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
During conference calls with cooperator, we decided which contaminants and the concentration levels to be tested. A selection of ARS carbons will be screened for adsorptive capacity. Progress was monitored through conference calls.
