采用灵敏、快速的亚化学计量放射化学方法研究了乙基、丙基、丁基、戊基和苄基黄原酸钾盐萃取汞的相对程度。研究了 pH 值对黄原酸汞配合物萃取到氯仿中的影响。研究发现，pH 12、11、10、9 和 5.5 的缓冲溶液是分别最大程度地萃取乙基、丙基、丁基、戊基和苄基黄原酸酯复合物形式的汞的合适介质。所开发的程序用于测定在安得拉邦奇托尔区八个地区收集的标准溶液和地质水样中的汞含量。
The relative extent of extraction of mercury with potassium salts of ethyl, propyl, butyl, pentyl and benzyl xanthates has been studied employing a sensitive and rapid substoichiometric radiochemical method. The effect of pH on the extractability of mercury xanthate complexes into chloroform was investigated. Buffer solutions of pH 12, 11, 10, 9 and 5.5 were found to be suitable media for the maximum extraction of mercury as ethyl, propyl, butyl, pentyl and benzyl xanthate complexes, respectively. The procedures developed were utilized for the determination of mercury content in standard solutions and geological water samples collected in eight parts of Chittoor district of Andhra Pradesh.
