摘要
本文研究了采用电解加复合稳定剂的方法制备FeO_4^(2-)絮凝剂的电化学与溶液化学过程机制,分析了OH^-膜平衡过程对FeO_4^(2-)形成的影响,探讨了FeO_4^(2-)水溶液分解的诱发因素,初步确定了FeO_4^(2-)电化学合成的最佳条件。研究结果表明,适宜的电量参数、合理的电解液组成和高效的OH^-膜渗透是顺利进行稳定化FeO_4^(2-)电解合成的二个要素。
The ferrate is an effective multi-functional water treatment reagent for its powerful oxidtion, flocculation or aid flocculation, adsorption and disinfection, so it possesses a very valable study and application future. This paper studies the electrochemical and solution chemical processes and mechanism of ferrate by the electrochemical method. In addition, the influence of OH membrane equilibrium on ferrate formation is analyzed and some inducing factors for ferrate decompositon are investigated. Based on the theoretical and experimental study, the optimum conditions for preparing ferrate is given primarily. The study results suggest that the proper electrochemical parameters, reasonable electrolyte composition and high efficient OH- membrane osmosis are three key factors for preparing stable ferrate flocculant.
