【摘要】 以可再生201×7型阴离子交换树脂为构晶离子的供体,与一定浓度的ZnSO4溶液,在搅拌条件下反应一定时间,制备纳米ZnO,并利用扫描电镜、微机差热天平及紫外-可见分光光度计对产物进行了表征,同时考察了纳米ZnO的光催化性.结果表明,离子交换法制备的纳米ZnO对有机物、有色废水等具有很强的光催化性.更多还原

【Abstract】 Nanometer zinc oxide was prepared by recycling zinc ion-exchange resins which acted as suppliers for ions composing crystal and a certain concentration of zinc sulfate solution were mixed and reacted at certain temperature for a given time with stirring.The products were characterized by SEM,differential thermal balance and UV-Vis spectrophotometer,and the photocatalytic activity of the nanometer zinc oxide was investigated.The results show that the nanometer zinc oxide had strong photocatalytic activity on organic compound and colored wastewater.更多还原
