Method of manufacturing a chromium hydroxide

Method for manufacturing chromium hydroxide of the present invention may be soluble in an acidic aqueous solution than chromium hydroxide obtained by the conventional manufacturing method to obtain a high chromium hydroxide, the method, the reaction liquid temperature is 0 ℃ or under conditions of less than 50 ° C., and an aqueous solution containing an inorganic alkaline aqueous solution and trivalent chromium, are added simultaneously to the aqueous medium, characterized in that to produce chromium hydroxide. It is preferred to maintain the pH of the reaction mixture during the addition of the aqueous solution and an inorganic alkaline aqueous solution containing trivalent chromium in the range of 7.0 to 12.
