Abstract

A highly selective molecularly imprinted polymer (MIP) to 4-Aminopyridine (4-Ap) target was synthesized starting with azobenzene monomers, which cross-linked initiated by 2, 2′‐azobisisobutyronitrile with the ethylene glycol dimethacrylate. The obtained sorbent, comprised of light-thermosensitive functions, was characterized using FTIR and SEM. The product was finally employed for the 4-AP target in solid-phase extraction. The effect of optimal parameters in the process was studied. The adsorption and release processes for 4-Ap drug delivery were investigated under various conditions, including temperature and radiation wavelengths. This study suggests a facile determination method high selectivity to 4-Ap adsorption/release in a real sample.
