摘要
研究了大量铬、镍中钛的分离方法。在一定条件下使三价铬氧化成 6价铬 ,再在氨性条件下使钛沉淀 ,大量铬、镍留在溶液中。将分离后的沉淀酸溶后用二氨替比林甲烷光度法测定钛。回收率为 93.7%～ 1 0 2 .4%。
A separation method of titanium separated from rich Chromium-Nickel-Vanadium was represented. After trivalent chromium was oxidized and became hexavalent chromium, titanium can be precipitated and separated from chromium-nickel-vanadium solution under ammonia condition. By employing acidic dissolution of this deposit, titanium can be determined by diantipyrylmethane spectrophotometer.
