Abstract: In order to effectively improve the ability of students majoring in applied chemistry to apply comprehensive knowledge and complete experiments, we recommend and implement a comprehensive chemistry experiment titled “Preparation and Characterization of Rare Earth Benzoate Complexes”. This experiment involves the preparation and composition analysis of rare earth organic complexes, along with the study of their luminescent properties. Additionally, students are introduced to various instrumental techniques, including EDTA complexometric titration, infrared spectroscopy, thermogravimetric analysis, and fluorescence spectroscopy. Through this experiment, students not only consolidate their basic experimental skills, but also develop their overall experimental capabilities while gaining a deeper understanding of the electronic structure and spectral properties of rare earth elements.
