| Abstract: | On the non-ionic sorbent Amberlite XAD-2 the sulphonated derivative of an aromatic complexing agent-Pyrocatechol Violet-was immobilized, and this chelate-forming resin was used for the preconcentration of Pb(II) and In(III) and for the separation of some metal ions. The PV-XAD-2 resin was adopted for the preconcentration of Pb(II) in tap-water. Very high preconcentration factors were obtained. |
