| 摘 要： | 为了探讨天然沸石对NH4^＋的吸附规律，以江苏镇江的天然沸石为实验对象，测试其矿物组成与化学成分，通过静态摇床法实验研究其对铵离子的吸附特性及阳离子的交换特性，进行吸附等温线实验。结果表明，实验沸石对NH4^＋吸附等温线符合Langmuir公式。根据数学分析，确定沸石的铵吸附容量。

| Abstract: | In order to discuss the regular absorption rules for ammonium with natural zeolite, the authors took the natural clinoptilolite occurred in Zhenjiang, Jiangsu as an experimental sample. Its mineral composition and chemical composition were tested. Their adsorption characteristic for ammonium was studied under batch experiment, and its adsorption isothermal lines were established. It is concluded that the adsorption isothermal lines met the formula Langmuir, and its adsorption capacity for ammonium was determined through mathematic analysis. |
