Document Type and Number:
Japanese Patent JP4336921
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method by which titanium is stripped from a titanium- containing extraction agent and can be separated and recovered. SOLUTION: In this method for stripping titanium from a titanium-containing acidic extraction agent, titanium is stripped from a titanium-containing acidic extraction agent by using hydrogen peroxide-added oxalic acid. The concentration of oxalic acid is preferably controlled to 0.05 to 1 mol/l, and more preferably to 0.5 to 0.9 mol/l. Further, the molar ratio between hydrogen peroxide and titanium is preferably controlled to the range of (1:1) to (50:1), and more preferably to the range of (5:1) to (20:1).
