Aluminosilicate-catalyzed electrochemical decomposition of ammonium cation (NH4+) in water was investigated using NH4+-saturated clinoptilolite and copper-nickel electrodes in the presence of different salts and acidic species. The results showed beneficial roles of chloride anion and moderately acidic media. NH4+ adsorbed by the zeolites was converted with a 98% selectivity into nitrogen. The process was found to obey zero-order kinetics in the presence of clinoptilolite and a first order process when NaCl is added. Beneficial buffering effects of the zeolite and acidic species were registered. Clinoptilolite turned out to act as both catalyst and NH4+ reservoir. These results allow envisaging effective and waste-free technology in treating NH4+-rich aqueous effluents through total electroconversion into nitrogen using low cost aluminosilicates. Clay minerals, soils, sludges and natural water turbidity are potential catalysts for this purpose.

铝硅酸盐催化的电化学从水中去除铵阳离子的动力学和选择性。

在不同盐和酸性物质存在下，使用NH4 +饱和斜发沸石和铜镍电极研究了铝硅酸盐催化的铵离子（NH4 +）在水中的电化学分解。结果显示出氯离子和中等酸性介质的有益作用。沸石吸附的NH4 +以98％的选择性转化为氮。发现该过程在斜发沸石存在下服从零级动力学，而在添加NaCl时服从一级过程。记录了沸石和酸性物质的有益缓冲作用。斜发沸石可同时充当催化剂和NH4 +储层。这些结果允许设想一种有效且无浪费的技术，通过使用低成本铝硅酸盐将总NH4 +转化为氮，可以处理富含NH4 +的废水。
