摘要
应用毛细管离子分析法，对硝酸镍中微量钴的测定进行了研究，其结果表明：１ —亚硝基萘—２ ，７ —二羟基—３ ，６ —二磺酸与 Ｎｉ２ ＋ 、 Ｃｏ２ ＋ 形成稳定的络离子，在４５０ ｎｍ 、２０ ｋ Ｖ、３５ ℃的测定条件下，５ 分钟内检测出硝酸镍中含钴量为０２８ ％ ．
Determination of Cobalt in Ni(NO_3)_2 with 1—Nitroso—2,7—dihydrexynaph- thalene—3,6—disulfonic acid(1N2,703,6S)by High Performance Capillary Electrophoresis. Showing that 1—Nitroso—2,7—dihydrexynaphthalene—3,6—disulfonic acid and Ni^(2+),Co^(2+)form the steady chelate anions,and under the determination condition of 35℃,20 kV、450 nm,in five minute Ni(NO_3)_2 contains 0.28% Cobalt.The proposed method was applied to the determination of Cobalt in Nickel salts.
