| 摘 要： | 考察了振荡时期温度、ＰＨ吸附效果的影响，通过吸附热力学实验，探讨了吸附机理，结果表明，温度是影响吸附效果的主要因素；等温吸附规律可用Ｆｒｅｕｎｄｌｉｃｈ模式和Ｌａｎｇｍｕｉｒ模式较好地描述；可能的吸附机理为：一是ＮＨ分子通过偶极力和氢键方面吸附，二是ＮＨ４通过离子交换面吸附。

| Abstract: | The effects of adsorption time,temperature and pH value of initial solution on the adsorption of ammonia nitrogenonto the activated FCCwaste catalyst were inspected.In addition,the mechanism for the adsorption was also studied in this paper.theresults showed that temperature is the main facter to affect the adsorption efficiency,The adsorption alw can be well described byFreundlich and Langmuir models .The possible adsorption mechanism is:NH3 is adsorbed by dipole force and hydrogen bond force,andnh4+ is adsorbed by ion exchage. |
