摘要
Abstract
The kinetics and thermodynamics of the adsorption of total flavonoids in Bupleurum by AB-8 macroporous resin were studied using the static adsorption method. The kinetics results show that the pseudo-second order kinetics model can better describe the whole adsorption process. The multicollinearity of curves fitted by the intra-particle diffusion model demonstrates that the adsorption rates at different stages are influenced by the pore size distribution. The thermodynamics results show that the adsorption process fits the Langmuir isothermal model in the studied temperature range. The thermodynamic properties,i. e. △GΘ <0,△HΘ = 10. 51 kJ/mol and ASΘ = 44. 15 J/(mol · K) , indicate that the adsorption process is spontaneous and endothermic.关键词
