近年来,极谱法与伏安法的研究与应用在继续发展,两法的区别在于指示电极,前者用滴汞电极,后者用固态的电极,如涂汞电极或非涂汞电极.金球镀汞电极就是其中之一.资料报导了各式电解池,但所有装置只适用滴汞法,其中自动装置复杂.本文研制了一种既适用滴汞电极,又适合固体电极的两用电解池.用滴汞测定时,汞自动滴落在储汞管里,防止了汞的溅漏污染.试液自流上方进样,空气与溶液自动分离,基本消除了对滴汞的影响.测定波高时关闭活塞,溶液相对静止,电位及波高稳定.我们采用方便的自来水作为动力,使试液自动进出电解室.为了防止自来水压入电解室,我们研制了一个自流加速吸液管,自来水流动后与电解池管道产生一个较大压力差.因此,实现了进出样自动化.本电解池经济、简单、实用方便.
In recent years, the research and application of polarography and voltammetry continue to develop. The difference between the two methods lies in the indicating electrode, the former using a drop of mercury electrode and the latter using a solid electrode, such as a painted mercury electrode or a non-coated mercury electrode. Ball mercury electrode is one of them.According to the report of the various types of electrolysis cells, but all devices only apply the mercury drop method, including automatic device complexity.In this paper, a drop of mercury electrode suitable for both solid electrode and dual-use electrolysis In the case of drop mercury measurement, mercury automatically dripped in the mercury storage tube to prevent mercury from splashing and splashing.The test solution was injected from the top of the stream and the air and the solution were separated automatically, basically eliminating the influence on drop mercury. When the piston is closed, the solution is relatively static, the potential and wave height are stable, and we use convenient tap water as the motive force to make the test solution automatically move in and out of the electrolysis chamber. In order to prevent tap water from entering the electrolysis chamber, we developed a self-accelerating pipette. And electrolytic cell pipeline to produce a greater pressure difference.Therefore, to achieve the kind of automation.Electrolytic cell economy, simple, practical and convenient.
