Lead-selective PVC membranes are presented. The membrane include the known cation-exchanger lead bis(i- butyldithiophosphate) (PbTP) and a new cation-exchanger diphenylmethyl-N-phenyl-hydroxamic acid (PMPHA). The electrodes of both types are Pb2+ responsive in Pb(NO3)2 solutions without Nernstian response to PbOH+ or PbNo3+. The working range is ppb 1.8-5.0 in the case of PbTP and pPb 2.3-5.3 if PMPHA was used as the ion-exchanger. The pH interference is 'anomalous' as is well known in the case of calcium-selective electrodes. The electrodes based on PMPHA provide selectivity to lead ions in the presence of Cu2+, HG2+, Hg2+ and Ag+.
