Abstract A comprehensive chemical experiment based major on physical chemistry knowledge, including also contents of inorganic chemistry and structural chemistry, is recommended here for practical teaching. Zeolitic-imidazolate framework compound of ZIF-67 was prepared by a simple precipitation method carried out at room temperature. The structure of the compound was characterized by powder X-ray diffraction, and the size and morphology of the product were studied by scanning electron microscopy. The solid-liquid adsorption process of ZIF-67 to remove aqueous organic dye of Congo red was studied by UV-Visible spectrophotometer. The adsorption isotherm and kinetics was studied in full detail. This comprehensive experiment fully combines the basic knowledge of chemistry, basic experimental skills and frontier academic research. It would deepen the students’ understanding of chemistry knowledge, improve their basic experimental skills and ability to carry out scientific research by applying subject knowledge comprehensively, further developing their divergent thinking mode and innovation ability.
