SP700 is a nonpolar resin suitable for vanillin (V) and syringaldehyde (S) adsorption.
Batch experiments were successfully fitted with Langmuir and Freundlich models.
Maximum adsorption capacities obtained: 0.663 (V) and 0.707 (S) g g−1dry_resin.
SP700 showed 46% more capacity for V than reported in literature for other resins.
Fixed bed experiments were described with the axially dispersed plug flow model.
