摘　　要：建立电感耦合等离子体原子发射光谱法测定羰基镍粉中砷、镉、铅、锌、锑、铋、锡、钴、铜、锰、镁、铝、铁、钙、钼、硅等杂质元素含量的方法。采用硝酸(3+2)溶解样品,考察了酸度对测定的影响,确定了各元素最佳的分析谱线。在标准溶液中,元素含量分别为0、0.025、0.1、0.5、1.0μg/mL时,十六种元素的强度与浓度呈现良好的线性关系,对应的相关系数均大于0.999。最终的加标回收率为94.0%~104.0%,相对标准偏差RSD<6.53%(n=7)。该方法有效的提升了羰基镍粉中多元素分析的效率,满足硬质合金生产工艺的要求。The method for the determination of impurity elements including arsenic,cadmium,lead,zinc,antimony,bismuth,tin,cobalt,copper,manganese,magnesium,aluminum,iron,calcium,molybdenum,and silicon in carbonyl nickel powder by inductively coupled plasma atomic emission spectrometry was established.Nitric acid(3+2)was used to dissolve the sample,and the effect of acidity on the determination was investigated.The optimal analytical spectral lines for each element were determined.At the range of 0,0.025,0.1,0.5,and 1.0μg/mL,the intensity and concentration of 16 elements showed a good linear relationship,and the corresponding correlation coefficients were all more than 0.999.The final recoveries were 94.0%~104.0%,and the relative standard deviation RSD was less than 6.53%(n=7).The method can effectively improve the efficiency of multi-element analysis in carbonyl nickel powder and meet the requirements of the cemented carbide production process.
