Abstract:The efficient solid-phase extraction (SPE) adsorbents for the detection of trace mycotoxins are challenging to prepare in an essential sample pretreatment. In this study, an efficient SPE adsorbent, an electrospun polystyrene/polyacrylonitrile nanofiber membrane modified by polydopamine (PDA@PS/PAN NFM), was prepared and characterized. It is shown that the introduction of PDA provided abundant amino groups and phenolic hydroxyl groups for the porous network structure of these nanofibers, which can contribute r… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
