  • Abstract

    A novel type PbS hollow nano-sphere bag burried in membrane fractions was designed and manufactured as carrier of lead ions on the PVC membrane ion selective electrode. The response of the electrode was linear relationship to the lead ion with concentration between the range of 1×10-2～1×10-5 mol·L-1 , with the slope of 26 mV/pC and the lower detected limit of 71×10-6 mol·L-1. PVC membrane of about 03 mm thickness was put in the lead ion solution with concentration of 1×10-1～1×10-2, 1×10-3～1×10-5 and 1×10-6 ～1×10-7 mol·L-1 , and the response time was 9～15, 20～45 and 55～70 s respectively. In the 1×10-3 mol·L-1 lead ion solution, the range of pH was 3～7 while electrode potential was stable and the silver ion had a certain interference on electrode.
