✦ Synopsis
A reversed-phase liquid chromatographic procedure for the determination of amino acids and copper(U)-amino acid complexes was improved and applied to studies dealing with adsorption and remobilization of copper from sediments in the presence of free and complexed amino acids. In particular, the adsorption by inorganic fractions of a marine sediment was investigated by means of batch equilibration experiments. The results indicate that two adsorption mechanisms, one due to electrostatic interaction and the other one based on hydrophobic characteristics of the considered species, are simultaneously possible. Scanning electron microscopy with electron probe microanalysis was utilized to provide further information.
