0.01M のAlamine 336およびAliquat 336によるバナジウムの溶媒抽出に関する研究

抄録

The extraction, stripping and separation of V from another metal ions with Alamine 336 and Aliquat 336 in kerosene were chiefly studied and these characteristics were clarified. Extraction of V from 0.01M vanadium sulphate solutions at about pH 3 with 0.01M Alamine 336 and at pH 2.5-8.5 with 0.01M Aliquat 336 were about 100%. The shaking times required for the extraction were about 20 min. with Alamine 336 and about 30 sec. with Aliquat 336.
The species that take part in the reaction were mainly H₂V₁₀O^4-₂₈ with Alamine 336 and H₂V₁₀O^4-₂₈, HV₁₀O^5-₂₈, V₁₀O^6-₂₈, V₄O^4-₁₂ with Aliquat 336. Stripping of V from Alamine 336 and Aliquat 336 were about 100% more than pH 8.8 with 0.1M (NH₄) ₂S0₄ solution and about 95% at pH 7 with 1M NH₄NO₃ solution, respectively.
Separation of V from the solution containing Fe²⁺, Cu²⁺, Ni²⁺, Mo (VI) and W (VI) were possible by the selection of optimum pH.
