ZnO/锂皂石复合材料的制备和吸附性能研究

Research on the Preparation and Adsorptive Properties of ZnO/Hectorite Composite to Methylene Blue

采用直接沉淀法制备氧化锌,合成了氧化锌/锂皂石复合材料,利用XRD、SEM等方法表征样品的结构和形貌,通过吸附动力学分析了氧化锌/锂皂石复合材料的吸附性能。结果表明:氧化锌/锂皂石复合材料对亚甲基蓝有很好的吸附性能,优于氧化锌和锂皂石。

Preparation of ZnO/hectorite composite material,testing its adsorption properties.Prepared by direct precipitation ZnO and ZnO/hectorite composite material.Characterization of the composite material,to analysis adsorption properties of the composite material that degrades of methylene blue solution.The results of SEM and FTIR indicate that the hectorite and ZnO has been fully composite,The properties of absorbing methylene blue solution of composite material is much better than standard hectorite.By direct precipitation method for preparing good morphology ZnO and ZnO/hectorite composite material.The adsorption efficiency of Composite material that modified by hectorite is Significantly improve.
