极谱分析工作中,经常接触汞。对于汞中毒的预防,应从多方面给予充分注意。由于汞的蒸气压较大(20℃时为0.0013毫米),在20℃时汞饱和的空气含汞量,超过国家最大允许浓度(0.01毫克/米~3)很大。因而,操作时偶一不慎而溅出了少量汞,由于小汞滴表面积大,容易蒸发。若通风不好而又不立即清除,很容易超过国家最大允许浓度。但细小的汞滴收集和清除颇为费事且较费时。所以,作者试验了用铜棒汞齐化后,作为捕集器,
Polarographic analysis of work, frequent contact with mercury. Mercury poisoning prevention should be given full attention from many aspects. Due to the large vapor pressure of mercury (0.0013 mm at 20 ° C), the mercury content in air saturated with mercury exceeds the maximum allowable concentration in the country (0.01 mg / m 3) at 20 ° C. Thus, occasionally accidentally splashed a small amount of mercury, due to the small mercury droplet surface area, easy to evaporate. If the ventilation is not good but not immediately clear, it is easy to exceed the maximum allowable concentration of the country. However, the collection and removal of small mercury droplets can be cumbersome and time-consuming. Therefore, the author tested the amalgamation with a copper rod, as a trap,
