摘要
论述了钴对电解锰生产的影响 ,提出了用硝酸氧化Co -DDTC络合物 ,在醋酸盐缓冲溶液中 5 -Cl-PADAB分光光度法测定电解液中钴的分析方法。摩尔吸光系数ε =1 13× 10 5L (mol·cm) (波长 5 70nm )。方法检测范围 0 0 5～ 1 2mg L(采样体积 10mL)。
This paper studies the influence of cobalt in processing of electrolytic manganese metal. It presents a special spectrophotometric determination of cobalt in acelate buffer solution with 5-Cl-PADAB which consists of two steps: oxidizing Cobalt complex with DDTC in nitric acid and spectrophotometric determination of cobalt in acelate buffer solution with 5-Cl-PADAB. It has find that the molar absorptivity reaches 1 13×10 5 L?(mol·cm) at 570 nm and the linear range of the method is 0 05～1 2 mg?L with a 10 mL samplc.
