摘要
除介绍了锆交联累托石的制备 ,研究了锆交联累托石对制药废水的吸附。结果表明 ,当交联累托石用量为 2 0 g/L废水 、pH =3 0、5 5℃振荡吸附 3 0min ,COD去除率可达 76%以上 ;其最大表观吸附容量可达 119mgCOD/g ;其等温吸附平衡可用Freundlich方程来描述。
The paper introduced the producing Zr-pillared rectorites and the experiment of dealing with pharmacy wastewater.The result showed that under the condition that the usage of Zr-pillared rectorites is 20g/L,pH=3.0,55℃,swaged adsorption for 30 min;the scavenging ratio reached to 76%,the adsorption capacity reached 119mgCOD/g.The adsorption isotherm was fitted well with the langmuir equation.
