- •
Vanillin/syringaldehyde (V/S) adsorption in ethanol:water (EW) onto SP700 was studied.
- •
Adsorbed amount of V/S is 68/83 times higher in water than in EW.
- •
After V/S adsorption from aqueous solution, more than 84% was desorbed with 6BV of EW.
- •
Concentration factors of 19- to 67-fold, depending on the loaded amount, were achieved.
- •
Modeling of the adsorption was performed with Linear and Freundlich isotherms.
