2-BENZILTIO 5-(4-AMINOFENIL)-1,3,4-OKSADIAZOL REAGENTINING ELEKTROKIMYOVIY XOSSALARI VA MIS (II) IONINI ANIQLASHDA QOʻLLANILISHI
##submission.downloads##
Ushbu maqolada 2-benziltio 5-(4-aminofenil)-1,3,4-oksadiazol reagentining elektrokimyoviy xususiyatlari siklik
voltamperometriya, xronoamperometriya usullari yordamida oʻrganilgan va mis (II) ionini aniqlashning elektrokimyoviy usuli
ishlab chiqilgan. Mis (II) ionini aniqlashga har xil erituvchilar tabiatining ta’siri: sirka kislota, DMFA, butil spirt va etil spirt
oʻrganildi, ulardan etil spirti 1,2 v kuchlanishda optimal sharoit ekanligi aniqlandi. Siklik voltamperometriya usulida 2-benziltio
5-(4-aminofenil)-1,3,4-oksadiazol reagentining mis (II) ioni bilan hosil qilgan kompleksining yarim toʻlqin potensiali 0,25 volt
ekanligi siklik voltaperometriya usulida aniqlandi.
