To develop highly selective molecular recognition adsorption materials, which are applied in petrochemical industry, pharmaceutical engineering and high value-added natural product development. With molecular recognition technology as the core, it is coupled with intelligent separation technology, active controllable polymer polymerization technology and permeable membrane separation technology respectively to prepare composite materials for functional adsorption, establish a variety of new separation/enrichment technologies and apply them to desulfurization, dephenolization and dephosphorization of petrochemical products. Purification of antibiotic and salicylic acid series products; And the extraction and separation of high value-added natural products such as plant protein, pigment, luteolin and allicin. The equilibrium, kinetic, thermodynamic calculation and correlation data of the solid-liquid adsorption process were studied. To study the selective removal of environmental pollutants such as metal ions, chlorophenol, antibiotic residues, active molecule of Traditional Chinese medicine, oil, etc.
