一种新型吸附材料的除磷性能研究

针对水体富营养化的磷，采用吸附法进行处理，制备出一种新型的除磷吸附剂，对水中磷酸盐的吸附性能进行了研究，结果表明，该吸附剂对磷酸盐的吸附速率很高，在酸性条件下，其最大吸附容量为34mg／g。当溶液pH值在1～3范围内，含磷浓度为50mg／L，吸附剂投加量为200mg，接触时间为2h，磷酸盐的去除效率可达98％以上；再生后的吸附剂容量变化不大，是一种具有较高应用价值的新型材料。

Study on a Type of Material with Phosphate Removal Characteristics

In order to remove the phosphorus that causes eutrophication, a new type of dephosphorization absorbent was prepared in the paper. The adsorption of phosphate was studied, and results showed that the adsorption would finished quickly in a short time and in acid solution, the adsorption capacity was 34 mg/g. When 200 mg of absorbent was added into solution with phosphorus of 50 mg/L and pH within 1 - 3, 98% of phosphorus could be removed in 2 h. No significant changes were found on the adsorption capacity after regeneration, which promised it a high application value.
