高纯汞的分析一般是按国家标准GB913-66方法进行,即蒸馏分离汞,以重量法测定残渣,然后用差减法求得汞量。但是,此方法化费时间。也有采用测定汞中杂质的方法,但需特殊设备。若用化学法测定杂质,则更繁琐费时。我们采用蒸馏分离汞,以硝酸分解残渣,用铜 Analysis of high purity mercury is generally carried out according to the national standard GB913-66 method, that is, distillation and separation of mercury, gravimetric determination of the residue, and then subtracted to obtain the amount of mercury. However, this method takes time. There are also methods for the determination of impurities in mercury, but special equipment is required. If the chemical determination of impurities, the more complicated and time-consuming. We use distillation to separate mercury, nitrate decomposition residue, with copper
