Abstract

Three sensitive and selective electrodes were developed for the determination of asenapine mallet. One electrode containing PVC membrane, ammomium renikate as an anion exchanger and dibutyl phthalate as a plasticizer (sensor I). Two carbon past ISE using phosphodiester acid and ammomium renikate as an anion exchanger (sensors II and III) and dibutyl phthalate as a plasticizer. The proposed electrodes showed a near-sensation response in the range from 1.00×10-5 to 1.00×10-2 mol/L for sensor I and 5.00×10-5 to 1.00×10-2 mol/L for both sensor II and III. The selectivity of the proposed electrodes to a number of interferences was investigated. Asenapine was successfully determined in pure form, pharmaceutical formulation and in presence of its oxidative degradation product.
