A poly(vinyl chloride) membrane electrode that is highly sensitive and selective for zinc ions has been developed by using tetrabutyl thiuram disulfide neutral carrier. This electrode incorporated the ionophore along with o-nitrophenyloctyl ether as a plasticizing solvent mediator and potassium tetrakis(p-chlorophenyl)borate as anion excluder; it exhibited a linearity range of 10-1-10-6M with a Nernstian slope of 28.0mV per decade at 25±1°C. The membrane electrode showed a good response to zinc ions in the useful pH range of 3.5 to 6.5, where interferences arise only from a few transition metals such as CuII and PbII.read more
