摘要

The extensive use of sulfonamides has caused serious ecotoxicological effects, sulfonamide antibiotics are difficult to remove when they are in their anionic form. In this work, a novel polystyrene supported ionic liquid (PS-CH2-[TSiIm][Cl]) material was prepared for the effective removal of sulfadiazine sodium (SDS). Results showed that the adsorption efficiency maintained relatively stable and high in a wide pH (6-10) and temperature (25-70 degrees C) ranges. SDS adsorbed onto the PS-CH2-[TSiIm][Cl] could be well evaluated by Langmuir model and the maximum adsorption capacity could be reached as high as 438.2 mgg(-1). Simultaneously, the PS-CH2-[TSiIm][Cl] exhibited excellent removal performance toward trace SDS at ppb level (0.005mgL(-1)). Common inorganic ions such as K+, Na+, Ca2+, and Cl- had no effect of on the removal of SDS even if their concentrations were 20000 times higher than that of SDS. And the PS-CH2-[TSiIm][Cl] was easy to regenerate without loss in adsorption performance. Additionally, the PS-CH2-[TSiIm][Cl] was applied to remove the SDS from environmental water samples. The possible adsorption mechanism was also investigated. (c) 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47981.
