冷原子荧光法测定硫化物单矿物中痕量汞

Determination of Hg in Sulfide Minerals by Hydride Generation-AFS

摘要: 针对辉锑矿、方铅矿、黄铜矿中主体元素Sb、Pb、Cu对原子荧光测定Hg的干扰,本文在20％王水介质中加入酒石酸溶液消除Sb的干扰,采用EDTA来消除Pb和Cu的影响。使得冷原子无色散原子荧光法测定Hg在硫化物类型的单矿物中得到扩大应用。

Abstract: A method for determination of Hg in mineral separates of. stibnite, galena or chalcopyrite by hydride generation-AFS is proposed. Interference from Sb is eliminated by addition of tartaric acid and Pb and Cu can be masked by EDTA. The method has been used
