||Understanding Variation in Partition Coefficient, K(d), Values. Volume III. Review of Geochemistry and Available K(d) Values for Americium, Arsenic, Curium, Iodine, Neptunium, Radium, and Technetium.
This is the third volume in the series that describes: (1) the conceptualization, measurement, and use of the partition coefficient parameter; and (2) the geochemical aqueous solution and sorbent properties that are most important in controlling adsorption/retardation behavior of selected contaminants. Volume I and II were published in 1999. Volume I of this document focuses on providing EPA and other environmental remediation professionals with a reasoned and documented discussion of the major issues related to the selection and measurement of the partition coefficient for select group of contaminants. The selected contaminants investigated in Volume II of this document include: chromium, cadium, cesium, lead, plutonium, radon, strontium, thorium, tritium(3H), and uranium. The contaminants discussed in Volume III include: americium, arsenic, curium, iodine, neptunium, radium, and technetium. This three volume report also addresses a void that has existed on this subject in both EPA and the user community.
