Abstract :The preconcentration of some divalent metal ions by complexation with carboxylphenylporphyrine (TCPP) and retention on conventional anion-exchange resins and nonionic sorbent was examined. Two different procedures - ligand in solution or immobilised on the solid sorbents - were evaluated as a function of pH. The selectivity order for TCPP-loaded resins was established as: Pb(II) > Ni(II) > Cd(II) > Cu(II) > Mg(II)
