In this study, the adsorption behaviors of a series of systematically designed resins with different physical textures and chemical characteristics were investigated towards sulfonic acid dyes and the adsorption mechanism involving physical and chemical adsorption was elaborately explored. The newly synthesized resins include the hyper-crosslinked resin series which possesses the largest physical adsorption capacity, aminated resin series which has the largest uploading of amino groups and aminated crosslinked resin series which was functionalized with amino groups after the optimization of physical structure. The aminated crosslinked resin AC-2-DETA displayed the best adsorption performance (325.63 mg/g) towards BA and the adsorption capacities increased by 93.0% compared to commercial resin H-103 and the superiority in adsorption is applicable to other dyes with diverse characteristics. Detailed investigation on chemical-physical adsorption interaction based on N₂ adsorption-desorption study revealed the significance of associating chemical modification with structure optimization. The former provided hydrogen bonding and electrostatic interacting sites and the latter regulated porous structure and BET surface area. The adsorption kinetics and thermodynamics were also studied to gain further understanding for the adsorption behaviors.
