Abstract
OBJECTIVE: To study kinetic characteristics of static adsorption of D201 resin aniou to ginkgo leaves flavone. METHODS: The adsorption isotherms of D201 resin anion under different temperatures were determined by HPLC, and adsorption kinetic curves of initial concentration were also determined. RESULTS: The adsorption of D201 resin anion to ginkgo leaves flavone was in line with Freundlich equation and Langmuir equation; adsorption kinetic regularity can be described with secondary velocity equation; main speed control step of adsorption was liquid membrane diffusion, and activation energy of adsorption was -10.328 5 kJ/mol. CONCLUSION: The conclusion can provide reference for further parification and separation of D201 resin anion to ginkgo leaves flavone.关键词
