Removal of Al-and Ca-Nitrilotriacetic Acid from Waters by Subsoils

Proceedings of the 1993 Georgia Water Resources Conference, April 20-21, 1993, Athens, Georgia.Synthetic chelating agents and the metals they carry can be environmental pol1utants. Chelating agents are organic molecules with two or more functional groups which bond metals by encircling them with ligand "arms". Metals, which would normally be stationary in soils and sediments, can be resolubilized and transported by chelating materials. Chelates are often used to scavenge metals in industrial processes and can carry metals into the environment. Preliminary research is needed to determine the kinetics of chelating agents being sorbed or degraded in order to further study the impact they, and the metals they carry, have on soils, sediments and waters. Chelating agents could have profound influences on the free toxic metal concentrations in waters in Georgia due to possible release from soils and sediments.Sponsored and Organized by: U.S. Geological Survey, Georgia Department of Natural Resources, The University of Georgia, Georgia State University, Georgia Institute of TechnologyThis book was published by the Institute of Natural Resources, The University of Georgia, Athens, Georgia 30602 with partial funding provided by the U.S. Department of Interior, Geological Survey, through the Georgia Water Research Institute as authorized by the Water Resources Research Act of 1984 (P.L. 98-242).
