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。
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 to the determination of Hg in sulfide minerals, with satisfactory results.
