利用不同粒径的沸石对水中磷的吸附性能进行初步研究。结果表明：投加量7 g，反应时间60min，温度35℃，pH 3～9时沸石对水中磷的吸附效果最佳；沸石对磷的吸附动力学过程适合用拟二级速率方程进行拟合，拟合系数接近1；吸附等温线符合Freundlich方程所描述的规律，温度越高，沸石对磷的吸附性能越好；在相同的温度条件下，粒径越小的沸石对磷的吸附能力越强。

The zeolite with different particle sizes was selected asadsorbent to examinethe adsorption performanceof phosphorus in water.The results showed that the optimal condition of adsorption of phosphorus by zeolite was a dose of 7g,60min of reaction time,35℃ of temperature,and 3~9 of pH value.The kinetics process of adsorption of phosphorus may be more suited to fit by pseudo -secondary order kinetics equation,and the fitting coefficients were close to 1 .The adsorption isotherm may be more suited to be described by Freundlich equation.The adsorp-tion performance of phosphorus by zeolite became betterwith an increase of temperature.Under the same condition of temperature,zeolite with smaller particle sizeshad higher adsorption capacity of phosphorus.
