| 摘 要： | 以吉林刘房子膨润土为研究对象，对原土进行了酸改性，并将酸改性膨润土用于水体中磷的吸附试验。结果表明：酸改性膨润土对磷有较好的吸附作用。最佳条件为：酸改性试验中膨润土（g）和改性剂（mL）的固液比为20：100，吸附实验中酸改性膨润土的投加量为0．5/100mL，吸附时间为4h。

| Abstract: | Bentonite of Jilin Liufangzi was modified by H2SO4,and it was used in the experiment of adsorption of phosphorus. The results showed that the adsorption capacity of bentonite modified by H2SO4 was much increased. The optimized dosage of bentonite modified was 20g/100mL in the experiment of acid modification under room temperature and 0.5g/100mL in the experiment of adsorption under adsorption time 4h. |
