| 摘 要： | ＩＣＰ－ＡＥＳ法测定矿渣中痕量金。称样５．００００ｇ于６５０℃灼烧后，用王水溶解，滤液通过ＴＢＰ萃取树脂色谱柱吸附，０．１ｍｏｌ／ＬＨＣｌ＋０．１ｍｏｌ／Ｌ硫脲混合淋洗液解脱。本法分析０．０５１ｇ／ｔ含量的金标样，结果与推荐值吻合。六次分析结果的相对标准偏差（ＲＳＤ）＜５％。回收率为９６％～１０４％。方法简便，快速和准确。

| Abstract: | Taking 5.0000 g of sample to be scorched,then,dissolve the scorched sample with aqua regia followed by filtration.The trace gold in the filter liquor are adsorbed in the chromatographic column containing TBP extracting resin and the adsorbed gold are eluted by the mixed solution of 0.1 mol/L HCI and 0.1 mol/L thiourea. Result of analysing sample of 0.051 g/t gold content coincides with the acknowledged value. Relative standard deviations of the six time's analysing results are less than 5% and the recovery rates are 96%-100%. This method is simple, speedy and accurate. |
