在电分析和电化学研究中,需要使用参比电极。饱和甘汞电极因其电位稳定、制作简单而常被采用。但是,饱和甘汞电极使用过程中由于电解质沿烧杯和盐桥向上蠕升,致使整个电极部分布满氯化钾晶体,时间一久,还会爬行到实验桌上。不仅影响美观,污染了环境,而且影响测量结果。有没有办法克服电解质的蠕升呢?有人建议使用硅胶膏(L、麦蒂斯,“极谱技术”科学出版社1958).我们经多次试验,采用石
In electrical analysis and electrochemical studies, reference electrodes are required. Saturated calomel electrode because of its potential stability, production is simple and often used. However, saturated calomel electrode due to electrolyte along the beaker and the salt bridge upward creep, resulting in the entire electrode partially covered with potassium chloride crystals, over time, but also crawl to the experimental table. Not only affect the appearance, pollute the environment, but also affect the measurement results. Is there any way to overcome the creep of electrolyte? It is suggested that the use of silicone paste (L, Matisse, “Polarographic Technology ” Science Press 1958. We have been tested several times, using stone
