In electrochemical desalination, an efficient ions transfer between positive and negative electrodes is necessary and highly desirable. Herein, a redox media, edible riboflavin-5′-phosphate sodium salt (FMN-Na), is successfully applied to carry out continuous desalination as flow electrolyte in a desalinated device. The desalination process is achieved by trapping Na⁺/Cl⁻ at positive/negative steams respectively with help of cation/anion exchange membranes. The removal efficiency can be up to 98.1 %. The salt removability and consumption rate are investigated under different current densities and salt concentrations. The flow rate of electrolyte and cyclic-ability are also examined. This green and pollution-free electro-catalytic technology will offer great potential for the safe and effective seawater desalination.

在电化学脱盐中，在正负电极之间进行有效的离子转移是必要的，也是非常需要的。在此，氧化还原介质，可食用的核黄素5'-磷酸钠盐（FMN-Na），已成功地用于在脱盐装置中作为流动电解质进行连续脱盐。脱盐处理通过捕集达到的Na ⁺ /氯^-分别在阳离子/阴离子交换膜的帮助下以正/负蒸汽进行处理。去除效率可高达98.1％。在不同的电流密度和盐浓度下研究了盐的去除率和消耗率。还检查了电解质的流速和循环能力。这种绿色无污染的电催化技术将为安全有效地海水淡化提供巨大潜力。
