Solvent extraction of a mixture ofPb II , Mn II , Fe III , Co II , Ni II and Cd II in aqueous perchlorate medium by a phosphorylated hexahomotrioxacalix[3]arene (calix-3) in dichloromethane shows a significant selectivity towards lead ions. The ligand can also be incorporated into a membrane to provide a new lead ion-selective electrode (Pb"-ISE). A plasticized PVC membrane containing 30% PVC, 53.5% ortho-nitrophenyloctylether (NPOE), 4.5% sodium tetraphenylborate (NaTPB) and 12% ionophore was… CONTINUE READING
