Studies on Extraction of Rhodamine B by Amino Acid Modified Zirconium MOFs
Metal-organic Frameworks(MOFs)have been the focus of research in various fields in re-cent years.Due to their porous,large specific surface area and adjustable pore size,their structures are easy to be modified,and they are widely used in the field of adsorption and separation.Using different carriers to carry out adsorption experiments on RhB in water,to improve the adsorption rate of RhB as much as possible,can greatly reduce the content of RhB in water,so as to reduce its harmfulness.In this paper,pyromellitic acid functionalized UiO-66-(COOH)2 was used as the carrier,and it was modified by glycine(Gly)and glutamic acid(Glu).Rhodamine B was extracted by changing the extraction conditions by single variable method,characterized by powder X-ray diffraction(XRD)and infrared spectrum(IR),and its adsorption capacity for Rhodamine B was studied by fluorescence spectrophotometry.
