试剂对微量汞分析的影响及其引起的“干扰异常”的排除

REAGENT INFLUENCE ON TRACE MERCURY ANALYSIS AND EXCLUSION OF CAUSED INTERFERENCE ANOMALY

用ＸＧ－冷原子吸收型数字测汞仪对水汞等进行纳克级别以下的极微含量分析。测量中加入的一些试剂影响测量数据的准确性和稳定性。对此笔者进行了一些实验研究。本文分析和介绍了测定中添加试剂的影响情况和一些实测数据分析实例；并提出了一般的解决方法，在地震和其他领域微量汞测量中有使用价值。

The trace analysis below ng grade is conducted for mercury using numeral mercury meter of XG cold atom absorbing type. The empirical study on the influence of additive reagent on accuracy and stability of measure data is conducted. Some examples and general soluble method for the influence of additive reagent on the analysis of real measure data presented. The measure method of trace mercury can be also used for seismic prediction and other fields.
