摘要：

Sensors for the potentiometric determination of mefenamic and phenylanthranylic acids are prepared on the basis of single- and the double-layer plasticized polyvinylchloride membranes. Ion pairs of perchlorate and mefenamic and phenylanthranylic acid with basic fuchsin are synthesized for the fabrication of membranes. The composition of compounds is confirmed by spectrophotometry and IR spectrometry. Effects of different factors on the electrode characteristics are studied, the composition of the membranes is optimized. The proposed procedure for the fabrication of double-layer membranes ensures the improvement of the properties of sensors for mefenamic and phenylanthranylic acids. The developed procedures are applied to the analysis of pharmaceutical preparations.
