  • 铅试金富集-火焰原子吸收光谱法测定含金工业污泥中的金……庄艾春,肖红新
  • 摘 要:含金工业污泥中的金具有回收价值,而对其的测定没有国家标准。采用铅试金富集-火焰原子吸收光谱法测定含金工业污泥中的金,实验对称样量、火试金配料、介质酸度等条件进行了优化。该方法测定结果的相对标准偏差为0.61 %~3.70 %,加入标准物质回收率为97.85 %~99.00 %,准确度和精密度良好,适用于含金工业污泥中金的测定。

    Determinationof gold in gold-bearing industrial sludge by lead assay enrichment-fire atomicabsorption spectrometry……Zhuang Aichun,Xiao Hongxin

    AbstractThe gold in gold-bearing industrial sludge has potentials for commercialrecovery.However,there is national standards for its determination.The paperdetermines gold in gold-bearing industrial sludge by lead assay enrichment-fireatomic absorption spectrometry.The test optimized the influence factorsincluding sample weight,fire assay materials and media acidity.The RSD of themethod is 0.61 %~3.70 %; the recovery rate of reference material is 97.85 %~99.00 %;the results are accurate and precise; the method can be applied tothe determination of gold in gold-bearing industrial sludge.
