将人造沸石用于废水除磷，除磷率只有10%~20%，效果不佳。用NaOH溶液、MgCl₂溶液浸泡后再用马弗炉焙烧的方法对人造沸石进行改性，并采用改性沸石作为吸附剂，对水样进行吸附除磷实验；采用单一变量的静态吸附实验来确定吸附剂用量、吸附时间、吸附温度、水样中磷含量等因素对改性沸石吸附容量的影响。结果表明，用3 g改性沸石处理15 mg/L的含磷水样，在25℃下吸附2 h时除磷率达到62.4%；用超声波代替传统振荡方式，在相同条件下除磷率可达到80%。

The removal rate of phosphorus is only 10%-20% if artificial zeolite is used to remove phosphorus from wastewater.Artificial zeolite is modified by NaOH solution, MgCl₂ solution soaking and muffle furnace roasting method.The modified zeolite is used as adsorbent to remove phosphorus in water samples.The dosage of adsorbent, adsorption time, adsorption temperature and phosphorus content in water samples are tested to get the influence of modified zeolite adsorption capacity.It is indicated that the removal rate of phosphorus can reach 62.4% when a 15 mg·L^-1 phosphorus water sample has been treated by 3 g of modified artificial zeolite at 25℃ for 2 h.If ultrasonic replaces traditional oscillation mode, the removal rate of phosphorus will reach 80% under the same conditions.
