Abstract
Soil pore water samples contain higher concentrations of metals and dissolved organic carbon than do fresh water samples. A method for the analysis of complexed and uncomplexed metals in soil pore water samples has been developed by applying sequential anion and cation separations, followed by neutron activation analysis on the separate solutions. Six metals (Al, Ca, K, Mg, Mn, and Na) were determined, and their relationships to pH and dissolved organic carbon were studied. The aluminum separation results are compared with results obtained by two established procedures for determining solution species of aluminum. The ion exchange separation may be combined with another analytical method if desired.
