研究了用微波炉消解铜精矿,原子吸收光谱测定其中As、Pb、Zn、As、Sb和Hg的方法。讨论了消解体系的选择和微波炉消解程序。样品经HNO_3-HCl一次消解便可连续测定6个元素,方法简便快速,与国标方法进行了比较,结果一致。
The method of digestion of copper concentrate by microwave oven and the determination of As, Pb, Zn, As, Sb and Hg in the concentrate by atomic absorption spectrometry was studied. Discussed the digestion system selection and microwave digestion procedures. The sample was digested with HNO_3-HCl once to determine 6 elements in a row, the method was simple and rapid, and compared with the national standard method, the results were consistent.
