【摘要】 采用水热共沉淀法合成钨酸镍纳米半导体材料,通过扫描电子显微镜（SEM）,X-射线衍射仪（XRD）,能谱仪（EDS）对其结构和形貌进行表征.以亚甲蓝溶液作为被吸附对象进行研究,分别考察NiWO₄的加入量,pH值,亚甲蓝的初始浓度,pH值,反应时间对其吸附性能的影响.实验证实,NiWO₄对亚甲蓝溶液具有很高的吸附性能,本研究为NiWO₄纳米半导体材料对有机染料废水的处理提供了一定的思路.更多还原

【Abstract】 Nickel Tungstate nano-semiconductor materials were synthesized by coprecipitationhydrothermal method,and their structures and morphologies were characterized by scanning electron microscope（ SEM）,X-ray diffraction（ XRD） and energy disperse spectroscopy（ EDS）. Taking methylene blue solution as the adsorbed object, the influences of the addition amount of NiWO₄,pH value, the initial concentration of methylene blue,pH value and reaction time on its adsorption performance were investigated. Experiments show that NiWO₄ has a good adsorption activity on methylene blue solution,which provides some ideas for the treatment of organic dye wastewater with NiWO₄ nanometer semiconductor materials.更多还原
