摘    要:利用共沉淀法制备复合铁铝吸附剂,研究了磷浓度、pH值、温度及共存离子对除磷效果的影响. 结果表明,复合铁铝吸附剂除磷效果显著,吸附容量随溶液磷浓度升高而升高,同等条件下,吸附容量是活性氧化铝的3.5倍;对磷的吸附作用以化学吸附为主,磷在吸附剂表面同时存在着非特性吸附和强的特性吸附;CO32-对除磷效果产生较强干扰,CO32-与PO43-在吸附剂颗粒表面存在着竞争吸附.

关 键 词:复合铁铝吸附剂  吸附  痕量磷  给水处理

Abstract:Iron-aluminum composited adsorbent was prepared by co-precipitation method and the influence of phosphorus concentration,pH value,temperature and interfering ions to phosphorus removal were studied.The results showed that the adsorbent possess remarkable effects on phosphorus removal.With increased phosphorus concentration,adsorption capacity of the adsorbent kept a renarhed growth.In the same conditions,the adsorption capacity of the adsorbent was 3.5 times compared with that of activated alumina.Phosphoru...
Keywords:iron-aluminum composited adsorbent  adsorption  trace phosphorus  drinking water treatment
