PURPOSE:To remove the titled inonic compd. by bringing an inorganic ion exchanger contg. metals such as Ti, Zr, As, Mo, and W and having a hydroxyl group into contact with the liquid contg. ionic compds. CONSTITUTION:An inorganic ion exchanger consisting of elements having 0.55- 1.0Angstrom ion radius and 1.3-2.2 electronegativity such as Ti, Zr, Sn, Pb, Ta, Mo, W, Co, and Ni and having a hydroxyl group is brought into contact with the liquid contg. ionic compds. About 0.1-100g ion exchanger is used per 1kg liquid contg. several hundred ppm ionic compds. |
