摘　　要：研究了钢渣、炉灰、蜂窝煤渣、天然土壤4种常用吸附剂对磷的吸附和解吸特征,结果表明4种吸附剂在振荡12h后达到吸附平衡,吸附量随着初始浓度的增加而增加。钢渣和天然土壤对磷的吸附效果明显(吸附量分别为4.39mg/g和3.35mg/g),炉灰和蜂窝煤渣效果次之(吸附量分别为2.27mg/g和2.14mg/g),因此钢渣可以作为最好的吸附材料。The four kinds of commonly used adsorbent （slag, ashes, slag honeycomb, natural soil） on phosphorus adsorption and desorption characteristics of four kinds of results show that the adsorbent in the oscillation to reach adsorption equilibrium after 12h, with the beginning of adsorption so that the concentration of increased. Steel slag and natural soil phosphorus adsorption effect（adsorption 4.39mg/g and 3.35mg/g）, the effect of ashes and slag honeycomb times （adsorption 2.27mg/g and 2.14mg/g）, therefore can be used as the best steel absorption materials.
