| 摘 要： | 通过静态实验研究了竹炭对氨氮的吸附性能和影响因素。实验结果表明,竹炭对氨氮的吸附过程遵循准二级动力学模型;竹炭对氨氮的等温吸附可用Langmuir和Freundlich等温模型拟合,相关系数R2达到极显著相关(P<0.01);在pH为4.93～9.03范围内,吸附量随着pH的上升而增加;温度升高有利于竹炭对氨氮的吸附。

| Abstract: | Experiment was conducted on adsorption characteristics of bamboo-charcoal,a new type of adsorbent for removing ammonium in water.Results indicated that the adsorption kinetics can be described by pseudo-second-order model and well fitted by both Langmuir and Freundlich equations.Influence of some parameters such as temperature and pH were also studied. |
