| 摘 要： | 本文通过测试分析，证实在冷原子吸收法测定汞的过程中，用３％ＨＮＯ３溶液代替５％ＨＮＯ３－０．０５％Ｋ２Ｃｒ２Ｏ７溶液作固定液，使标准溶液和水样测试条件一致，空白吸光度降低，样品吸光度误数更准确，读差更小。

| Abstract: | Through the tests and analysis.The paper has proved that 3% HNO3 solution can replace 5% HNO3 0.05% K2Cr2O7solution as fixative in testing mercury by the method of cold atom absorphotometry.Which accords the testing conditions of standard solutions with that of water sample,reduced the blank absorbance,and makes the sample absorbance readings more accurate,has samller errors. |
