本研究的范围是通过离子交换从模拟废水中去除铵。该研究着眼于有机物对铵离子交换平衡吸收的影响。离子交换剂包括天然沸石斜发沸石和两种聚合物交换剂Dowex 50w-x8 和Purolite MN500。研究的有机化合物包括柠檬酸和许多蛋白质。从废水中去除铵和有机污染物的传统方法是生物处理，但离子交换具有许多优点，包括处理冲击载荷的能力以及在更广泛的温度范围内运行的能力。结果表明，在大多数研究案例中，有机化合物的存在增强了离子交换剂对铵离子的吸收。 (C) 2003 Elsevier Science Ltd. 保留所有权利。
The scope of this study was the removal of ammonium by ion exchange from simulated wastewater. The study looks at the effect of organics upon ammonium ion exchange equilibrium uptake. The ion exchangers included a natural zeolite clinoptilolite, and two polymeric exchangers, Dowex 50w-x8, and Purolite MN500. The organic compounds studied included citric acid and a number of proteins. The traditional method for removal of ammonium and organic pollutants from wastewater is biological treatment, but ion exchange offers,a number of advantages including the ability to handle shock loadings and the ability to operate over a wider range of temperatures. The results show that in most of the cases studied, the presence of organic compounds enhances the uptake of ammonium ion onto the ion exchangers. (C) 2003 Elsevier Science Ltd. All rights reserved.
