✦ Synopsis

This paper describes relations between the degree of complexation calculated with a mathematical model (FISUHEB and REISSIG, 1984) and the ion-exchange and migration behaviour of iron(I1, In)-compounds in a simulated aquifer. I n general, the bonding of the complexes to the soil matrix becomes stronger with increasing positive charge. Negatively charged or neutral complex compounds do not show any, or show only slight interactions with the soil matrix. By complexation it is possible to achieve great di€ferences in the migration behaviour of a particular
