上海第二分析仪器厂新产品 DJS-52型控制电位电解仪现已成批生产。很多单位1973年就已到货。但对该仪器的性能和使用方法提出了一些问题,要求我们解答。为此,特作一综合性答复,以供参考。但必须指出:本文并不能代替该厂所附的使用说明书。使用说明书是不能不看的,而且要仔细看。问:控制电位电解仪和一般电解仪有什么不同?电解仪是利用电化学原理的基本分析仪器之一。一般的电解仪是恒电流式的,在电解过程中阴极的电位变化不定,无法控制。但控制电位电解仪的阴极电位则始终被控制在某一选定的数值以内,大大提高了电解淀积的选择性,因此要比一般的电解仪优越得多。
Shanghai Second Analytical Instrument Factory new product DJS-52-type control potential electrolysis device is now mass-produced. Many units arrived in 1973. However, some questions have been asked about the performance and usage of the instrument, asking us to answer it. For this purpose, we should make a comprehensive reply for reference. However, it must be pointed out: This document does not replace the manual attached to the plant. Instructions can not help but read, but also to look carefully. Q: What is the difference between the control potential electrolyzer and the general electrolyzer? Electrolyzer is the use of electrochemical principles of the basic analytical instruments. The general electrolyzer is galvanostatic, the potential of the cathode during the electrolysis varies indefinitely, can not be controlled. However, the potential of the cathodic electrode of the control potential electrolyzer is always controlled within a selected value, which greatly improves the selectivity of the electrodeposition and is therefore much superior to the general electrolytic cell.
