  • New organoselenium selective ligands are presented which are intended for the determination of kinemetal ions in a sample and are used as complexing agents in a dispersive liquid-liquid microextraction procedure for copper and zinc ions. The method is characterised by a shortened extraction time,minimal organic solvents and lower solvent quantities as well as easy handling and high preconcentration efficiency.
