摘要
利用高分子微球模板法,将凹土与PS微球混合并进行离心沉降,制备成复合体,再通过高温烧结去除PS微球,制备出多孔结构凹土,利用热重分析仪(TG)、电子显微镜(SEM)、全自动氮吸附比表面积测试仪(BET)、X射线能谱仪(EDS)、X射线衍射仪(XRD)等对多孔结构凹土进行表征。利用干燥器法研究普通凹土与多孔凹土对甲醛的吸附性能。结果表明,制备多孔结构凹土的最佳烧结温度为350℃,凹土与PS微球的质量比为1∶4,多孔结构较好;在室温为18℃,玻璃干燥器容量为24 L条件下,多孔凹土质量为6 g时,对甲醛的吸附性能最佳。
Polystyrene microsphere and palygorskite were mixed in water and centrifugal settled to form complex, then the complex was sintered in oven to form porous palygorskite. The porous palygorskite was characterized with TG, SEM, EDS, XRD, BET. Adsorption property of porous palygorskite for formaldehyde was investigated with desiccator method. The results show that, the best sintering temperature for preparing porous palygorskite is 350 ℃, the mass ratio for palygorskite and polystyrene microsphere is 1 ∶ 4. In 24 L desiccator, at 18 ℃, 6g porous palygorskite has the best adsorption for formaldehyde.
