鉴于环境保护的关系,近年来我国分析工作者探索用固体电极代替滴汞电极,如金银蘸汞电极、银基汞膜电极、铂基汞膜电极的正向极谱研究和应用方面做了许多工作。而银基汞膜电极以它的制作简(?)、使用方便和良好的重现性引起人们的极大兴趣。银基汞膜电极在氨性底液中测定锌、镉、铜是较为成熟的,它被我们一年多的生产实践所证实。但是至今对于酸性底液中其它元素的测定进展仍然缓慢。特别是在盐酸—氯化钠底液中测定铅,还未见有资料报辺。
In view of the relationship between environmental protection, in recent years, our analysts have explored the use of solid electrode instead of drop mercury electrode, such as gold and silver dipped mercury electrode, mercury-based mercury film electrode, platinum-based mercury electrode forward polarographic studies and applications A lot of work The silver-based mercury film electrode with its production of Jane (?), Easy to use and good reproducibility aroused great interest. Silver-based mercury electrode in the determination of ammonia in the liquid zinc, cadmium, copper is more mature, it is more than a year of our production practices confirmed. But so far the determination of other elements in the acidic bottom liquid is still slow. In particular, hydrochloric acid - sodium chloride solution in the determination of lead, but no data reported 辺.
