MIL-53(Fe)复合材料对废水中双氯芬酸钠的吸附
Adsorption of diclofenac sodium from wastewater by MIL-53(Fe) composite materials
摘要
Abstract
Fe-MOF materials MIL-53(Fe)and MIL-53(Fe)-10FA were prepared by solvothermal method,and their adsorption properties for diclofenac sodium(DCF)in aqueous solution were investigated.The adsorption behavior of the two MOF materials to DCF follows the pseudo-second-order kinetic model,and the adsorption process belongs to chemical adsorption.The adsorption equilibrium isotherm conforms to the Langmuir adsorption isotherm model and is monolayer adsorption.The surface morphology of MIL-53(Fe)-10FA modified by formic acid was different from that of MIL-53(Fe).The crystal size was larger than that of MIL-53(Fe).The pore size,specific surface area and total pore volume increased after modified.The content of oxygen-containing functional groups also increased.The adsorption capacity of MIL-53(Fe)-10FA for DCF was significant,and the maximum adsorption capacity of Langmuir isotherm fitting was 652.29 mg/g.The adsorption mechanism mainly includes hydrogen bonding and π-π stacking between benzene rings and benzene rings.关键词
