摘要
本文提出了在煤油溶液中用对丙烯基苯甲醚萃取金的新方法,对金的萃取条件及其在原子吸收分析中的应用进行了研究。在0.5mol/L HC1及10％对丙烯基苯甲醚——煤油萃取条件下,金的萃取率在98％以上。原子吸收灵敏度及检测限得到了改善。方法已成功地应用于矿石及浸出渣液中微量金的测定。
A preconcentration with solvent extraection-flame ZAAS has Leen developed for the determination of micro gold in ores. The extraction of gold with p-propenyl phenyl methyl ether in kerosene and the effects of the factors on the extraction are inves tiga ted. The linear range for determination of gold is 0-40μg/ml. The percentage extraction above 98%. This method is sensitive and convenient. It has Leen applied, to ore and waste liquid Samples with satisfactory results.
