Adsorption of Acetamiprid and Phenol from Water in Binary Components System with Adsorption Resins Modified with Proline

The adsorption of acetamiprid and phenol in water onto the resin of ZHP02 modified with proline based on NDA150 was investigated from the static experiment at different temperatures in single component system and binary components system. The adsorption capacities and adsorption selectivity for acetamiprid and phenol in waste water were tested. The results showed that the adsorption was fitted by Freundlich model, and the adsorption of acetamiprid or phenol on ZHP02 was an exothermic process. The cooperative adsorption existed in binary components system when the equilibrium concentration was higher. The adsorption of acetamiprid onto ZHP02 had little change in the presence of phenol, but the adsorption of phenol onto ZHP02 was weakened significantly in the presence of acetamiprid. The electrostatic force between acetamiprid and adsorbent was stronger than phenols, so acetamiprid was adsorbed preferentially onto ZHP02.
