Preparation, characterization and photocatalytic properties of rare-earth ibuprofen-phenanthroline complexes

In this experiment, europium(III)-ibuprofen-phenanthroline complexes, dysprosium(III)-ibuprofen-phenanthroline complexes and terbium(III)-ibuprofen-phenanthroline complexes were prepared separately, established a ternary solid complex system, performed a series of characterization of the system, and studied the application of the rare-earth-ibuprofen-phenanthroline complex system. In the experiment, the three ternary complexes were characterized by elemental analysis, infrared analysis, ultraviolet analysis, fluorescence analysis, thermogravimetric analysis, etc., and the chemical composition of the complexes was determined, and the data and spectra obtained were analyzed. The rare-earth ternary complex was successfully prepared by a simple and feasible method. The analysis results found that the characteristics and performance of the ternary complex were enhanced, and its physical and chemical properties were explored. The successful preparation of rare earth-ibuprofen-phenanthroline ternary complexes provides a certain scientific basis and reference for the study of determining the content of ibuprofen (IBU) in vitro, and also provides a new method for the synthesis of rare-earth ternary complexes. The reason why rare-earth materials can be used as catalysts is determined by their own photoelectric characteristics. In this paper, through the experimental test of catalytic performance of IBU and different rare-earth complexes, it is found that Tb complex has the best catalytic performance, and the degradation rate of phenol can reach 64.8% in 6 h.
