Potentiometric pH sensors based on polymer film were prepared by electropolymerization of the monomer nickel(II)-4,4',4'',4'''-tetraaminophthalocyanine (NiTAPc) or copper(II)-4,4',4'',4'''-tetraaminophthalocyanine (CuTAPc) on glassy carbon (GC) electrodes. The polymer of metal tetraaminophthalocyanine (p-MTAPc) film coated electrodes show a slope of 55 +/- 1 mV/pH (at 20 degrees C) and nearly Nernstain potentiometric response to pH over the range of pH 1-13. The electrodes possess good potential reproducibility and high selectivity, and are useful sensing devices in pH determination and end-point indication of acid-base potentiometric titration.
基于聚合物膜的电位pH传感器是通过在玻碳（GC）电极上对单体镍（II）-4,4',4'',4'''-四氨基酞菁（NiTAPc）或铜（II）-4,4',4'',4'''-四氨基酞菁（CuTAPc）进行电聚合制备的。金属四氨基酞菁（p-MTAPc）膜涂覆电极在20℃时显示出55±1 mV/pH的斜率，并且在pH 1-13范围内对pH具有近乎能斯特电位响应。这些电极具有良好的电位重现性和高选择性，是用于pH测定和酸碱电位滴定终点指示的有用传感装置。
