Abstract

Ushbu tadqiqot ishida Fe³⁺, Al³⁺ va Bi³⁺ kationlarining etanol-suv va propanol-1-suv aralash erituvchilar muhitida elektrometrik usullar yordamida aniqlash imkoniyatlari o'rganilgan. Potentsiometrik va voltamperometrik usullar qo'llanilgan holda turli xil erituvchi aralashmalarida metall kationlarining elektrokimyoviy xossalari tahlil qilingan. Tadqiqot natijalari shuni ko'rsatdiki, organik-suv aralash erituvchilar muhitida metall kationlarining redoks potentsiallari o'zgarib, selektiv aniqlash imkoniyatlari yaxshilanadi. Etanol-suv aralashmasida Fe³⁺ ioni uchun eng yuqori sezgirlik kuzatilgan, Al³⁺ ioni esa propanol-1-suv muhitida yaxshi natijalarga ega bo'lgan. Bi³⁺ ioni ikkala erituvchi aralashmasida ham barqaror elektrokimyoviy javob bergan.
