Lead-selective solvent polymeric membrane electrodes based on selected thiacrown ethers, poly(vinyl chloride) (PVC), the plasticizer bis(2-ethylhexyl)phthalate ["dioctyl phthalate" (DOP)], and potassium tetrakis(p-chlorophenyl)borate (KTpCPB) (50mol%, relative to the ionophore) as anionic sites are described. The potential measurements were done in the presence of acetate buffer (pH 4.00) and for successively diluted stock solutions of 10-2 M Pb(NO3)2. Potential-pH profiles of membranes based on selected thiacrown ethers demonstrated lack of H+ interference within a wide pH range. The effect of the sample solution composition as well as the inner reference solution on the selectivity and detection range were demonstrated.
