摘要
采用干燥的杨树叶粉末,探讨其对水中氨氮的吸附性能。结果表明,p H变化对氨氮吸附效果影响较小;相同氨氮初始浓度条件下,随着投加量增加,单位质量杨树叶粉末对氨氮的吸附量明显减少;初始氨氮浓度越大,单位吸附量也越大。杨树叶粉末对氨氮的吸附遵循Langmuir及Freundlich等温吸附模型。
Dry poplar leaves powder was used to investigate the adsorption properties of ammonia nitrogen in water. The results showed that the variation ofpH had little influence on ammonia nitrogen adsorption. At the same initial ammonia concentration, unit adsorption capacity decreased obviously with dosage increased, and unit adsorption capacity increased with initial concentration rose. The adsorption isotherm of ammonia adsorption on poplar leaves powder followed Langmuir and Freundlich isotherm model.
