| 摘 要： | 比较了经HCl和CaCl2,MgCl2改性后的煤渣对磷的吸附效果,研究了HCl改性煤渣对磷的吸附性能.结果表明,改性煤渣对磷的吸附能力从大到小依次为:HCl改性煤渣、CaCl2改性煤渣、MgCl2改性煤渣,其吸附量分别为47.24,19.58,14.50 mg/kg.原煤渣与HCl改性煤渣在振荡24 h后均达到吸附平衡,吸附量随初始磷浓度的增加而增加,对磷的吸附更符合Langmuir等温方程,对磷的最大理论吸附量为265.58 mg/kg.改性煤渣具有更好的除磷效果,可用HCl改性煤渣提高除磷效率.

| Abstract: | The effect of phosphorus removal with HCl-,CaCl2-and MgCl2-modified coal cinder,and the phosphor adsorption characteristics of HCl-modified coal cinder were investigated in present study.The results showed that their capacity of phosphorus removal appeared in the order of HCl,CaCl2,MgCl2,being 47.24,19.58,14.50 mg/kg,respectively.Phosphorus adsorption on the HCl-modified coal cinder reached equilibrium in approximately 24 h,and the adsorption capacity of phosphorus increased with increasing initial phosphor... |
