MAQOLA ANNOTATSIYASI

quote
Ushbu maqolada reniy metallini ajratib olish, qayta ishlash boyitish usullari haqida umumiy ma’lumot berilib, bugungi kunda reniyning asosiy qo‘llanilishi aviatsiyada gaz turbinalari uchun super qotishmalarda bo‘lib, neftni qayta ishlash katalizatorlarida foydalanish umumiy iste’molning taxminan 10% ni tashkil qiladi. Reniy -1 dan +7 gacha bo‘lgan bir nechta oksidlanish darajasiga ega, eng keng tarqalganlari +7, +6, +5 va +4. U bir oksidlanish holatidan ikkinchisiga osonlik bilan o‘zgaradi, bu jarayon reniy metallini katalizator sifatida ishlatish uchun eng muhim metal hisoblanadi. Ba’zi sulfat kislota va boshqa aralashmalarni o‘z ichiga olgan eritma, erituvchi ekstraktsiyasi yoki qattiq qatlamli ion almashinuvi orqali reniyni qayta tiklashga tayyorlash uchun qayta ishlash haqida ma’lumot berilgan.
