Ion selective electrode for 2,4-dichlorophenoxyacetic acid.
An electrode responsive to 2,4-D (2,4-dichlorophenoxyacetic acid) was constructed by dissolving tetrazolium derivatives as an ion exchanger in a liquid membrane. The electrode exhibited rapid and Nernstian response to solutions of 2,4-D over the concentration range 10(-1) to 10(-4)M. The presence of diverse substances such as acetate, benzoate, and 3-indoleacetate showed no appreciable effect on the electromotive force of the electrode.
