Concentration of Miglitol on Adsorption Effect of Equilibrium and Kinetics
Concentrations of miglitol on the adsorptive capacity effect of resin were investigated.The pseudo first and second order equations were used to describe the kinetic process of ion exchange. The results showed that adsorption of miglitol onto resin is fast and can reach approximate equilibrium after 2.5h. Langmuir model is suitable to describe the equilibrium adsorption.By linear fit of the pseudo first and second order equation and comparing the R2 value of correlation coefficient, it finds that the R2 value of the pseudo second order equation is bigger, and concludes that the ion exchange process is described by the pseudo second order equation.
