以锆、铝、钛(Zr、A1、Ti)多金属鞣制废弃物为原料,采用共沉淀法制备 Zr- A1-Ti 复合氧化物(ZAT-M),并形成纳米介孔型吸附功能型材料。采用综合热分析(DTA-TG)、X 射线衍射(XRD)、扫描电子显微电镜(SEM)和比表面积及孔径测试对 ZAT-M 进行表征。结果表明,ZAT-M 体系中由单质氧化物和交联氧化物组成,ZAT-M 可有效去除鞣制废水中的 ED-TA-Cr,吸附方式主要以表面吸附和静电吸附为主。
The mesoporous adsorption functional material of Zr-Al-Ti composite oxide is use Zr,Al,Ti multi-metal tanning waste as raw material and prepared by Zr-A1-Ti(ZAT-M)and using coprecipitation method.The ZAT-M is characterized by thermal analysis (DTA-TG),XRD,SEM,the specific surface area and pore size test.The results show that:ZAT-M system is composed of elemental oxides and crosslinking oxide,ZAT-M could effectively remove EDTA-Cr in wastewater by surface adsorption and electrostatic adsorption.
