【Abstract】 [Purposes] In response to the insufficient adsorption performance of commercial resins for water-soluble substances, this study improved the selective adsorption capacity of the resin for target pollutants in pharmaceutical wastewater through molecular design and surface modification, providing a new solution for wastewater treatment and resource recovery. [Methods] The adsorption performance of modified resin for oxiracetam in aqueous solution was investigated through isothermal adsorption and kinetic experiments, with comparative studies using NDA99 and NDA150 resins. [Findings] Results demonstrated that the sulfamic acid-modified adsorption resin(HGY-1) exhibited the optimal adsorption capacity for oxiracetam, achieving peak performance at 303 K. The adsorption isotherms of oxiracetam on HGY-1 resin were well described by both Langmuir and Freundlich models. The dynamic adsorption process followed pseudo-first-order kinetics, with intraparticle diffusion identified as the primary ratelimiting step. [Conclusions] This study presents a novel adsorption material for the separation, recovery, and resource utilization of the active oxiracetam component from pharmaceutical wastewater. Furthermore, this approach holds significant potential for industrial wastewater treatment and product purification.更多还原
