Study of sorption of monoethanolamine on H and Me forms of hydrated zirconium dioxide (HZD) in relation to the pH of the equilibrium solution and nature of the modifier cation and of the outer-sphere anion showed that HZD is sorbed on Me forms of HZD both by ion exchange and by ligand-exchange mechanisms. Sorption of MEA is greater on HZD in the Me form than in the H form, and depends on the content and nature of metal ions in the sorbent. Sorption of MEA and of its complexes with copper(II) ions on the Cu/sub SO/sub 4// form of HZD was accompanied by desorption of copper(II); this suggested the possibility of separating monoethanoamine complexes of copper (II) and cadmium(II).
