摘要
实验研究了动态条件下活性氧化铝对水体中磷的吸附,并对活性氧化铝进行了再生。结果表明,随着吸附水量的增加,磷去除率逐渐下降,在试验特定条件下,磷去除率可达到99.6%。流量对吸附效果也具有重要影响,最适吸附的pH为5~6。经过0.1 mol/L的NaOH溶液处理过的活性氧化铝可进行循环吸附。
Activated alumina was studied for removing phosphate from the dynamic water, and the activated aluminum was recovered. The results showed that: with the increase of adsorption water, phosphorus removal rate decreased gradually;in the specific test conditions, the phosphorus removal rate can reach 99.6%. Besides, flow rate also has an important influence on the adsorption rate;the optimum condition of pH was 5 - 6. The activated alumina treated by NaOH (0.1 mol?L?1) could be used for cyclic adsorption.
