- Abstract
This work reports a molecularly imprinting polymer based on environmentally friendly and non-toxic ZnO quantum dots for the selective detection sulfadimidine. The MIP@ZnO was prepared by sol–gel method, which usedZnO quantum dots, TEOS, APTES, ammonia as signal materials, cross-linker, function monomer, and initiator, respectively. Result proved that MIP@ZnO exhibited excellent selective fluorescence quenching in the presence of sulfadimidine, good linear relationship in the range of 0–40 μmol L−1 with a correlation coefficient (R2) of 0.98547 was obtained, and the imprinting factor was 2.83. Furthermore, MIP@ZnO has been successfully applied for detection SM2 in real samples with the spiked recoveries ranging from 95.6 to 99.8% with RSD below 2.38%.
