测定硫酸镍中杂质的方法,有许多资料报导过。作为试剂的分析有国家和部颁标准方法,这些方法为硫酸镍的生产提供了检验的标准。但是由于大量镍基体存在,对少量杂质测定有影响,为消除其干扰,又多采用有机试剂萃取分离,这不仅使测定的手续繁杂,而且又危害操作者的健康。当前,原子吸收分光光度法广泛地被应用着,它具有筒便快速等特点,是一般化学分析方法所不及的。本文就应用原子吸收光谱法测定硫酸镍中杂质进行了研
Determination of impurities in nickel sulfate, there are many data reported. As a reagent analysis, there are national and ministerial standards methods that provide a test for the production of nickel sulphate. However, due to the existence of a large number of nickel matrix, a small amount of impurities affect the determination, in order to eliminate its interference, but also the use of organic reagent extraction and separation, which not only complicate the determination procedures, but also endanger the health of operators. At present, atomic absorption spectrophotometry has been widely used, it has the characteristics of cylinder will be fast, etc., is less than the general chemical analysis methods. In this paper, the application of atomic absorption spectrometry for the determination of impurities in nickel sulfate was studied
