Abstract

A multisensory system of the "electronic tongue" type was developed based on glassy carbon electrodes modified with PEC@GO, PEC@SWCNT, PEC@CB and PEC@CP composites for the identification of pharmaceutical preparations of naproxen using differential pulse voltammetry. To improve the reliability of voltammetric recognition of pharmaceutical preparations of naproxen, chemometric data processing using PCA and SIMCA was proposed. It was shown that the multisensory system of the "electronic tongue" type correctly distinguishes 100% of the samples. To achieve such a degree of recognition, the multisensory system should include at least 4 sensors. The accuracy of recognition was tested on 3 samples of commercially available naproxen pharmaceuticals: "Nalgesin", "Teraliv", and "Nexemezin", produced by different manufacturers.
