三嗪羧酸锆介孔材料发的合成及其对有机分子吸附行为的研究-有机化学专业毕业论文.docxVIP

三嗪类羧酸锆介孔材料的合成及其对有机分子吸附行为的研究 (3)研究了新型三嗪类羧酸锆介孔材料(ZrTATB)对Rh B和DNBP吸附的热力 学和动力学特征。结果显示介孔材料对I让B和DNBP的吸附行为利用Langmuir等温吸 附式和Freundlich吸附等温式均可很好的拟合。Freundlich等温式拟合数据表明介孔材 料对Rh B的吸附属于优惠吸附。介孔材料吸附Rh B和DNBP的过程均适合使用二级 动力学方程。吸附过程都是膜扩散和内扩散共同作用的过程。热力学计算结果表明介孔 材料对Rh B和DNBP吸附过程均为吸热过程并且向着熵增大的方向进行。 关键词：羧酸锆介孔材料；吸附；罗丹明B；DNBP；废水处理 万方数据  大连理工大学硕士学位论文 Synthesis of Triazine Zirconium Carboxylate Mesoporous Materials and Its Study the Adsorption Performance of Organic Molecules Abstract W ith the development of agricultme and industry，water pollution has become more and more serious。Rhodamine B(RhB)is one of the most important water-soluble synthetic dye， which has been widely used as food additives，but now it Can only be used for dyeing industry， since it has been identified as carcinogenicity．2-Secbutyl·4，6一dinitrophenol(DNBP)is a typical example of nitro·substituted phenols，it is widely used as an insecticide in agriculture and an high temperature inhibitor in the petrochemical industry，it also has the very strong biological toxicity．A mass of highly toxic and poor biodegradability organic wastewater are produced in the process of above two kinds of compound production and use．The waste water has serious harm to public health and hindered futher development of social．Therefore， find effective method to remove organic pollutants from wastewater become the focus of aUention．At present a lot of methods about removing pollutants from wastewater Was reported，but only adsorption method has universal applicability，no secondary pollution，low energy consumption and high utilization rate of repeat．Mesoporous material has been widely used as a carder，adsorption and storage，due to its unique physical properties，such as large surface area，the highly uniform channel and easy to modify the hole wall． In the paper，by using cyanuric chloride，toluene，zirconium tetrachloride，SDS and other raw materials synthesis of triazine zirconium carboxylate mesoporous materials has rich pore structure and large surfac
