Ishda turli ion almashuvchi smolalardan fovdalangan holda murakkab sulfatlar eritmalaridan iborat vanadiv sorsivasi o'rganildi. Vanadiv (+4) va vanadiv (+5) konsentratsivasi titrimetrik metod bilan aniqlandi. Tajribalarda modelli eritmalardan foydalanildi. Temir (+3) va alyuminiy (+3) ionlari asosiy kation aralashmalari sifatida mavjud bo'lgan kislotali sulfat eritmalardan iborat vanadiv sorbtsivasi o'rganilgan. Vanadiv bilan birgan amfolit temirni ham samarali sorbsiva qilinishi belgilandi.
Tayanch iboralar: murakkab sulfatli eritmalar, ion almashuvchi smola, model eritma, vanadiv sorbsivasi, sulfat eritmalar, temir sorbsivasi, temir va alyuminiy aralashmalari, kam kislotali muhit, perikis vodorodning oksidlangan eritmasi, amfolit, kationit va anionit.
This work studies the sorption o f vanadium from complex sulphate solutions using a variety o f ion exchange resins. The concentration o f vanadium (+4) and vanadium (+5) is determined titrimetrically. The studies used a model solution. Sorption o f vanadium from acidic sulphate solutions containing as basal cation impurity ions o f iron (3) and aluminum (+3) was examined. It was established that iron effectively absorbs with vanadium ampholyte.
Key words: complex sulphate solutions, ion exchange resin, model solution, vanadium sorption, sulphate solutions, iron sorption, aluminum and iron impurities, weak acid medium, oxidation o f solution with hydrogen peroxide, ampholyte, cationite and anionite.
