Removal of ammonium ion (NH(4)(+)) from leachate from Odayeri sanitary landfill, located in the European part of Istanbul, was examined using Gördes (Turkish) clinoptilolite. The effects of pH, flow rate, ammonium concentration and competitive cations on the removal efficiency were investigated in both batch and column studies. Thomas model were used to analyze the breakthrough data. Nonlinear least square method was applied for fitting the column data. The competitive effect was observed more effective in lower ammonium concentration and higher cation concentrations. Conditioning and regeneration using NaCl improved removal efficiency of ammonium from leachate.
使用戈尔代斯（土耳其）斜发沸石对位于伊斯坦布尔欧洲部分的奥代耶里卫生填埋场渗滤液中的铵离子（NH₄⁺）去除情况进行了研究。在间歇式和柱式研究中，考察了pH值、流速、铵浓度和竞争阳离子对去除效率的影响。采用托马斯模型分析穿透数据。应用非线性最小二乘法对柱数据进行拟合。在较低的铵浓度和较高的阳离子浓度下，竞争效应更为显著。使用氯化钠进行预处理和再生提高了渗滤液中铵的去除效率。
