        <p>This article studies the synthesis and the properties of new ionophores used in the development of ion-selective electrodes (ISE) for the detection of drugs. In the course of the research, selective ionophores were created for the preparations dibazol, trimecaine and pyridoxine on the basis of dodecatungstophosphoric and dodecamolybdophosphoric acids. The synthesis processes, the methods of electrode preparation, the concentration of the solutions and the influence of pH were analysed in depth. These methods are inexpensive, easy to perform and highly accurate, and can therefore be widely applied in pharmaceutical analysis. On the basis of the results obtained, the practical significance of developing new selective electrodes was substantiated.</p>

        <p>В данной статье изучаются синтез и свойства новых ионофоров, используемых при разработке ионселективных электродов (ИСЭ) для обнаружения наркотиков. В результате исследования созданы селективные ионофоры для препаратов дибазола, тримекаина и пиридоксина на основе дододецилвольфрамовой кислоты и додецилмолибдофосфата. Были подробно проанализированы процессы синтеза, методы подготовки электродов, концентрация раствора и влияние pH. Эти методы недороги, просты в исполнении и высокоточны, поэтому их можно широ ко использовать в фармацевтическом анализе. На основании полученных результатов обоснована практическая значимость разработки новых селективных электродов.</p>

Tadqiqotda dododekowolframofosfat va dodekomolibdofosfat kislotalari asosida dibazol, trimekain hamda piridoksin preparatlari uchun selektiv ionoforlar yaratildi. Sintez jarayonlari, elektrod tayyorlash usullari, eritmalar konsentratsiyasi va pH ta‘siri chuqur tahlil qilindi. Ushbu usullar arzon, oson bajariladigan va yuqori aniqlikka ega bo‘lib, farmatsevtik analizda keng qo‘llanilishi mumkin. Olingan natijalar asosida yangi selektiv elektrodlar ishlab chiqishning amaliy ahamiyati asoslab berildi.</p>
