  • 硫代硫酸盐浸金溶液中金量测定方法的研究……高振广,刘正红,关国军,杜兆欣,孟宪伟
  • 摘 要:硫代硫酸盐法浸金的研究越来越多,硫代硫酸盐浸金溶液中金量的测定具有重要现实意义。实验分别采用直接酸化-活性炭吸附法、铁还原-活性炭吸附法、火试金富集法、过氧化氢氧化-酸化法、液溴氧化-酸化-活性炭吸附法及过氧化氢+液溴氧化-活性炭吸附法等多种方法测定硫代硫酸盐浸金溶液中的金量,最终确定过氧化氢+液溴氧化-活性炭吸附法测定结果重现性好,准确度高。该方法测定结果的相对标准偏差4.34 %7.31 %,加入标准物质回收率96.00 %102.00 %,且方法简单,适合样品的批量测定。

    Study onthe determination of gold content in thiosulfate gold leaching solution……GaoZhenguang,Liu Zhenghong,Guan Guojun,Du Zhaoxin,Meng Xianwei

    AbstractStudy on gold leaching with thiosulfate has beenincreasing,contributing to the determination of gold content in thiosulfategold leaching solution.The experiment determines gold content in thiosulfategold leaching solution by direct acidification-activated carbon adsorption,ironreduction-activated carbon adsorption,fire assay enrichment,hydrogen peroxideoxidation-acidification,liquid bromine oxidation-acidification-activated carbonadsorption and hydrogen peroxide+liquid bromine oxidation-activated carbonadsorption respectively.Finally,the hydrogen peroxide+liquid bromine oxidation-activatedcarbon adsorption has good reproducibility and high accuracy.The RSD of theresults is 4.34 %7.31 % and the recovery rate of reference materials is 96.00 %102.00%.The method is simple and convenient for batch testing of samples.
