Construction of hollow fiber stirring bar based on dummy molecularly imprinted polymers for the selective determination of organophosphorus pesticides in food samples

, respectively. In the spiked food sample analysis, recovery rates ranged from 61.61% to 91.41%, with relative standard deviations (RSDs) between 4.01% and 6.91%. These findings indicated that the synthesized DMIPs@CG161M composite possessed excellent selective adsorption performance for organophosphorus pesticides in food samples, highlighting its potential as an efficient adsorbent for practical applications.
