Abstract
The adsorption characteristic of paeoniflorin was investigated in adsorption thermodynamics and kinetics of AB-8 and D101 resins in the static adsorption work. The experimental results showed that the adsorption of paeoniflorin on two resins belonged to monolayer adsorption and in accordance with Langmuir isotherm equation. The process of adsorption was in line with the first order kinetic equation. The adsorption process was exothermic and the adsorption behaviour was in nonlinear adsorption stage. All the adsorption process was ended in 1 h. The adsorption behaviour of paeoniflorin on D101 was better than AB-8 resin. The results could be used to guide the separation experiments of paeoniflorin on macro porous resin.
