柱芯电极光谱法测定西藏斑岩铜矿中的铜、钼、银、铅、锌、砷、钨和铋

DETERMINATION OF Cu, Mo, Ag, Pb, Zn, W, Bi, AND As IN PORPHYRY OF TIBET BY SPECTRO GRAPHIC METHOD

本文研究了柱芯电极测定西藏斑岩铜矿中8个主次要元素,并与用其他电极测定的结果进行了对比实验。本文还讨论了组分影响及消除方法。对铜矿区样品测定,其RSD(n=15)为Cu±3.3%,Mo±4.1%,Ag±3.7%,Pb±6.5%。Zn±6.5%,As±7.3%,W±6.9%以及Bi±6.9%。用化学分析,外检和标样验证了方法的可靠性。

Eight elements in copper mineral of porphyry of Tibet has been determined by spectrographic method, and has been compared with other analytical method. The matrix effect and its eleminating method are discussed. The RSD(n=15) of eight elements are Cu±3.3%, Mo±4.1%, Ag±3.7%, Pb±6.5%, Zn±6.5%, As±7.3%, W±6.9% and Bi±6.9%, respectively. The probability of this method has been checkedd with chemical analysis and other method.
