| 摘 要： | 采用几种铝盐与铁盐,对相同粒径的颗粒活性氧化铝进行了吸附剂改性,并以优选了的改性方案为基础,研究了不同吸附剂粒径对吸附效果的影响。结果表明,活性Al2O3经改性后的静态吸附量是未改性的1.5～2倍;动态试验中,改性活性Al2O3的穿透时间为1.5～3.3d。用Al2(SO4)3和Fe2(SO4)3改性活性Al2O3的除氟效果较好。Φ1～2mm改性活性Al2O3的除氟性能远比Φ2～3mm改性活性Al2O3的好,前者的静态吸附量是后者的1.5倍左右,动态试验中,前者的穿透时间为11d,远长于后者(3.3d)。 |

| Abstract: | A series of granular activated alumina samples have been modified with different aluminum and iron salts,and a comparative study of their adsorption performance in fluoride removal was carried out. The effect of the diameter of the granular sorbent particles on adsorption performance was also investigated. The results showed that the defluoridation performance of the activated alumina was significantly enhanced by modification,and the static adsorption capacities of the modified activated alumina samples we... |
