摘要
本文研究了在空气-乙炔火焰中于pH6—8的水相介质直接进行贵金属铂(1V)的测定方法。测定的灵敏度0.5μg/ml 1％;2.5μg/ml,RSD(n=4)1.26％。在部分铜镍矿和黄铁矿地质样品中进行人工模拟试验,表明该法是可行的,可以测定同类地质样品中0.000 x％以上的铂。
This paper presents an alalytical method of directly determining the precious metal element Pt on the air—C_2H_2 flame in the medium of water with pH ranging from 6 to 8. The sensitivity of this method is of 0.5 μg/ml 1% and the determination of geological samples with 2.5μg/ml Pt results in a RSD of 1.26%(n=4). This simple and practical analytical method has been simuleted artificilly in copper, nickel samples and pyrite and proved to be feasible. Geological samples with Pt content over 0.000X% can be determined by this new method.
