摘要
用电感耦合等离子体发射光谱法测定铜镍矿、铅锌矿石中铜、镍、铅、锌、钴,样品用盐酸-硝酸溶解,在选定的测量条件下以ICP-AES测定溶液中的Cu、Pb、Zn、Co、Ni的含量.对国家一级标准物质进行测定,方法精密度(RSD,n=12)为Cu2.92%～6.62%,Pb1.88%～2.61%,Zn1.30%～2.05%,Co6.90%,Ni2.23%.本方法具有线性范围宽、干扰少、快速、简便、检出限低等优点.用于实际使用,结果满意.
A method to determine Cu, Ni, Pb, Zn and Co in copper - nickel ore and lead - zinc ore by inductively coupled plasma atomic emission spectrometry is reported in this paper. The samples are dissolved in HCl - HNO3. Under the selected mesurement conditions, the contents of Cu, Ni Pb,Zn and Co are determined by ICP - AES. The method has been applied to the determination of national standard reference materials with precision（RSD,n = 12）, which are 2.92% - 6.62% for Cu, 1.88% - 2.61% for Pb, 1.30% - 2. 05% for Zn, 6.90% for Co and 2.23% for Ni, respectively. The method has the advantages of wide linear range, less interference, rapidity, simplicity and low detection limit.
