Investigation of Static Absorption Properties for Geniposide with SP825 Macroporous Resin
Objective: To optimize adsorption conditions of geniposide on SP825 macroporous resin and investigate its adsorption equilibrium
thermodynamics and kinetics. Method: Based on single factor tests
response surface methodology was adopted to optimize adsorption conditions of geniposide with adsorption rate as index
isotherm adsorption model
kinetic curve and thermodynamic parameters of geniposide on SP825 resin were measured. Result: Optimum adsorption conditions were as follows:the concentration of sample solution 83 g·L-1
pH of 2.79;The maximum adsorption capacity was 247 mg·g-1.Adsorption equilibrium was well fitted by Freundlich formula
and kinetics process could be formulated by pseudo-second equation. Conclusion: Adsorption of geniposide was an spontaneous exothermic process
which could benefit from low temperature
adsorption rate was mainly controlled by liquid membrane diffusion.
