Abstract
Ushbu maqolada Fe(III) ionining nitrozo-R-tuzi bilan kompleks hosil qilish xususiyatlari hamda reagentni PPF polimer tashuvchisiga immobilizatsiya qilish jarayoni o‘rganilgan. Kompleksning fizik-kimyoviy va analitik tavsiflarini aniqlash uchun Tolmachyovning grafik metodidan foydalanilgan. Tadqiqot natijasida Fe(III)–nitrozo-R-tuzi kompleksining haqiqiy molyar so‘ndirish koeffitsiyenti εxaq = 8,0×104 l·mol-1·sm-1 hamda kompleks hosil bo‘lishining muvozanat konstantasi Kmuv = 6,25×104 ekanligi aniqlandi. Olingan natijalar immobilizatsiyalangan nitrozo-R-tuzi asosida Fe(III) ionlarini sorbsion- spektroskopik usulda aniqlash uchun sezgir va barqaror analitik tizim yaratish imkoniyatini ko‘rsatadi.References
