Synthesis of molecularly imprinted monolithic fibers for solid-phase microextraction of acetaldehyde from head-space of beverages stored in PET bottles

► We synthesize an acetaldehyde-imprinted monolithic fiber. ► It selectively extracts acetaldehyde from head-space of beverages stored in PET bottles. ► The fiber shows promising mechanical and thermal stability. ► The derivatization step is not necessary. Good linear range and long durability are the other advantages.
