| 摘 要： | 本文建立了直接火焰原子吸收测定聚合氯化铝中总铬的新方法。该法以亚硫酸钠为还原剂,用硫酸钠作干扰抑制剂消除大量基体铝对测定铬的干扰。测定结果的相对标准偏差为1.40％～7.56％,回收率在92.2％～100.2％之间。方法简便、快速,测定结果满意。

| Abstract: | A new method for direct determination of total chromium in polyaluminium chlode by flame atomic absorption has been established. The method was based on eliminating the interference caued by a great deal of matrix aluminium with sodium sulfate in the prence of sodium sulfite as a reductant. The result shows that the relative standard deviation was 1.40%-7.56% and the recoveries was 92.2%-100.2%. It waa simple and rapid. Satisfactory results were obtained. |
