2008 Annual Report 1a.Objectives (from AD-416) The objectives include: (1) Lab scale column adsorption studies with pure ammonia gas to determine the manure and plant-based carbons with the best adsorption efficiency along with the comparative studies of commercial grade carbons. (2) Preliminary studies on the adsorption capacities of the carbons with relation to direct poultry manure emissions which are comprised primarily of ammonia. (3) Compile the data for the submission of a minimum of one peer reviewed publication. 1b.Approach (from AD-416) The objectives stated are an integral part of the project plan referenced above. This work will expedite the accomplishment of the goals stated in the plan with relation to the examination of ammonia adsorption capabilities of the manure and plant-based carbons. 3.Progress Report Completed (in collaboration with ARS in Florence, SC) experiments to test if activated carbons made from animal waste could remove ammonia from air. The results are being evaluated and the work will be published when completed. The progress is monitored via periodic emails and phone conversations.
