Carbonate Ion-Selective Membrane Electrode

A liquid membrane electrode has been developed with Nernstian response and a high selectivity for carbonate ion. The electrode responds rapidly to carbonate in the 10-2M to 10-6M range with a selectivity for carbonate over chloride, sulfate, and phosphate of at least 103 and negligible bicarbonate response. The electrode properties appear to be suited to chemical, biological, chemical, and oceanographic measurements.
