原子吸收分光光度法测定钨铁合金中镍、钴、铜、锰

Determination of nickel,cobalt,copper and manganese in ferrotungsten alloys using atomic absorption spectrophotometry

镍、钴、铜、锰是钨铁产品中的杂质,国家标准规定了杂质元素的含量。为确保产品品质,需测定钨铁中的镍、钴、铜、锰元素的质量分数。探讨了连续测定方法测定钨铁中镍、钴、铜、锰的质量分数,结果表明方法操作简单、省时,节约成本。

Nickel,cobalt,copper and manganese are impurities in ferrotungsten products.The state standards stipulates the content of impurity elements.In order to ensure the product quality,it is necessary to determine the mass fraction of nickel,cobalt,copper and manganese in ferrotungsten.This paper discusses a continuous determination method for the mass fraction of nickel,cobalt,copper and manganese in ferrotungsten.The result showed it was simple,time-saving and cost-effective.
