| 摘 要： | 本文所述方法是将工业硫酸定量稀释，直接雾化进入ＩＣＰ激发，测定其中砷和铁的光谱强度和含量。绘制校准曲线用标准溶液，加入与测定样品相同量的分析纯硫酸为基体。该方法快速、简便，合成标准样品分析结果与标称值吻合，进口工业硫酸样品中砷、铁含量测定结果与国外检验结果、国家标准方法检验结果基本吻合。

| Abstract: | The method dealt with in this paper includes the following procedure:dilute 50mL sulphuric acid sample to 100mL with deionized water,then directly atomized into ICP torch.The same amount of analar or aristar grade sulphuric acid is added as matrix,achieving matrix-matched,and satisfactory calibration. Analytical result of standard sample and import industrial sulphuric acid is satisfying. |
