electron microscopy. The nanoparticles showed the excellent adsorption properties towards reactive black 5 as a reactive dye. The adsorption studies have been carried out at different pH values, various temperatures, and adsorbent doses. It was found that the removal process follows the second-order kinetics and the Freundlich adsorption isotherm.
溶胶-凝胶法制备了尖晶石Fe 1.95 Mn 0.05 NiO 4纳米颗粒。尖晶石结构的特征在于差热分析,X射线粉末衍射,傅立叶红外光谱,透射电子显微镜和扫描电子显微镜。纳米颗粒显示出对作为反应性染料的反应性黑5的优异吸附性能。已经在不同的pH值,不同的温度和吸附剂剂量下进行了吸附研究。发现去除过程遵循二级动力学和弗氏吸附等温线。
