Abstract

Sorption equilibria in several systems: Cu(II)–goethite, HEDP–goethite, Cu(II)–HEDP–goethite
(Cu(II)–EDTA–goethite, for comparison) have been studied and possible mechanisms for sorption process
have been suggested. In presence of chelating agents both remobilization and immobilization of metal can be
observed depending on complex stability and structure as well as solution acidity. The influence of chelating
agents on metal sorbed state in natural and artificial systems has been analyzed.
