摘要
研究以改性煤基活性炭为吸附剂对F-进行动态搅拌吸附试验,探讨了吸附时间、溶液pH值、干扰离子等,对改性煤基活性炭除氟性能的影响,试验表明,煤基活性炭经浓硫酸和磷酸改性后,对F-具有良好的去除性能,且用磷酸处理的活性炭除氟效果比用浓硫酸处理的除氟效果好,在一定的条件下其对F-的去除率可达到94%。
Modification of coal-based activated carbon as adsorbent of dynamic F-mixing as- say to explore the adsorption time, solution pH value, such as interfering ions on the adsorp- tion properties of adsorbent, testing showed that the concentration of coal-based activated carbon by sulfuric acid and phosphoric acid modified for F- has a good removal performance, under certain conditions of its F- removal efficiency can reach 94 %.
