AI Technical Summary
Existing technologies are difficult to effectively enrich and analyze ultra-low concentrations of amphetamine-type drugs in complex environments and biological matrices, and suffer from problems such as template leakage and poor selectivity.
A molecularly imprinted polymer gel membrane with alternative templates was developed. Using synephrine as an alternative template, the molecularly imprinted polymer was prepared by bulk polymerization and combined with membrane extraction technology to achieve highly selective adsorption and enrichment of amphetamine-type drugs.
It achieves highly selective enrichment and high recovery rate of trace amphetamine-type drugs in water, avoids template leakage, and has a simple and low-cost preparation process, making it suitable for the analysis of large-volume water samples.
