摘  要:
对硝酸钙泥、硝酸镁泥两种化工废渣的磷吸附特性进行了研究。结果表明:用Langmuir方程能很好地拟合300℃焙烧后的硝酸钙泥硝酸镁泥和500℃焙烧后的硝酸钙泥硝酸镁泥对磷的等温吸附。300℃、500℃焙烧后的硝酸钙泥、硝酸镁泥的磷最大吸附量分别为37.45、32.36、35.59、28.82mg/g,表面吸附强度因子分别为1.5615、0.2946、0.2948、0.2882mL/g,最大缓冲能力分别为58.48、9.53、10.49、8.31mL/g。对磷的吸附效果最好的是300℃焙烧后的硝酸钙泥。300℃、500℃焙烧后硝酸钙泥、硝酸镁泥对磷的去除率达到83%~99%左右。去除率最好的是300℃的硝酸钙泥。

摘  要:
This article studies thecharacteristics of Phosphorus adsorption of Calciun nitrate mud and Magnesium nitrate mud.The results show that adsorption of the 300℃,Calciun nitrate mudand Magnesium nitrate mud and 500℃Calciun nitrate mud Magnesium nitrate mud could well be simulated by the Langmuir equation.The maximum adsorption capacities of300℃,500℃Calciun nitrate mud and Magnesium nitrate mud are 37.45,32.36,35.59and28.82mg/grespectively,the adsorption equilibrium intensity factors are 1.5615,0. 2946,0.2948and0.2882mL/g,and the maximum buffer are 58.48,9.53,10.49and8.31mL/g.Thusthe best result is of300℃Calciun nitrate mud.The 300℃,500℃Calciun nitrate mud and Magnesium nitrate mud phosphorus of removal rate are around83%~99%.Itshows that the resultof 300℃Calciun nitrate mudis best.
