| 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。

| Abstract: | 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 37.45,32.36,35.59 and28.82mg/grespectively, the adsorptionequilibrium intensity factors are 1. 5615,0. 2946,0. 2948and0. 2882mL/g, and the maximum buffer are 58.48,9.53,10.49andS. 31mL/g. Thusthe best result is of 300℃ Calciun nitrate mud. The 300℃ ,500℃ Caleiun nitrate mud and Magnesium nitrate mud phosphorus of removal rate are around83%-99 %. hshows that the resultof 300℃ Calciun nitrate mudis best. |
