| 摘 要： | 在定量测试分析的基础上，讨论了保护剂和还原剂对水汞观测数据的影响。指出，分析纯硫酸的汞含量因生产厂家的不同而不同，有时可达地下水中汞含量的几百倍。对水汞微量分析而言，优级纯硫酸比分析纯硫酸更好。建议先用无汞蒸馏水做空白对照，然后再观测泉水，并以水样测值减去空白对照值，所得才是真正的泉水汞含量。

| Abstract: | The influence of the oxidation and reduction agent to the mercury observational data is discussed based on the quantitative test and analysis. It indicates that the mercury content of the analytical reagent H 2SO 4 is different with different production manufactory. Sometimes it amounts to several hundreds times of the mercury content in groundwater. For the mercury trace analysis, a guaranteed reagent H 2SO 4 is better than an analytical reagent. It is suggested that the blank control should be measured using distilled water without mercury before observing the spring water every time. The measured value of water sampling minus the measured value of blank control will be the true mercury content of spring water. |
