Analysis of diazepam residues in aquatic products based on magnetic molecularly imprinted polymers

, respectively, with recoveries ranging from 89.36% to 104.43% and relative standard deviations (RSD) of 1.22-5.30%. The satisfactory spiked recoveries and low RSD values indicate high sensitivity and good reproducibility. The strategy of using 2-chlorodiphenylketone as a dummy template constitutes an important highlight of this method, which fundamentally avoids potential false positives and quantification errors caused by template leakage in traditional molecular imprinting techniques. In summary, a magnetic molecularly imprinted polymer-based analytical method was established for the selective and accurate determination of diazepam residues in fish samples.
