电化学除镍研究进展

摘要
现有处理技术难以稳定达标。除镍的方法很多,如化学沉淀、离子交换、膜过滤、吸附、萃取、生物法以及电化学法等。其中电化学法是将电解质溶液通上电流,在阴极和阳极上分别发生还原和氧化反应的过程,快捷、方便且处理效果显著,基本不需添加化学物质,也不会造成二次污染。由于电化学系统的可控性及快速性,反应过程可在较小空间内进行,与其他方法相比占地面积小很多。基于此,本文主要对电化学除镍进行了简要的分析。
The existing processing technology is difficult to meet the standard stably. There are many methods to remove nickel, such as chemical precipitation, ion exchange, membrane filtration, adsorption, extraction, biological and electrochemical methods. Among them, electrochemical method is the process of electrolyte solution on current, reduction and oxidation on cathode and anode respectively. It is fast, convenient and effective. It basically does not need to add chemical substances, nor does it cause secondary pollution. Because of the controllability and rapidity of the electrochemical system,the reaction process can be carried out in a small space and occupies much less space than other methods. Based on this, the electrochemical nickel removal is briefly analyzed in this paper.
