- 中文摘要: The solvent extraction of vanadium by a chloroform solution of .alpha.-benzoin oxime was investigated. The most favorable condition for the extraction has been found in the pH range of 1.8 to 3.0 in sulfate or chloride buffer solutions, but with better extraction efficiency when sulfate was used. A solution of 2*10/sup -2/M.alpha.-benzoin oxime in chloroform was used, and 1*10/sup -4/ to 2*10/sup -2/M vanadium(V) was extracted favorably in about 89% yield by a single extraction, and in about 97% yield by a double extraction. The effects of shaking time, concentration of .alpha.-benzoin oxime, and diverse ions have also been investigated. Vanadium(V) can be readily extracted without interference in the presence of copper(II), aluminum( III), iron(III), silver(I), zirconium(IV), and chromium(III).
