“…The complexity of the sample matrix aggravates the difficulty in the analysis of trace levels of ZEN in food samples [6,7]. In this respect, the enrichment and separation of ZEN and its derivatives from the sample matrix are necessary to reduce the interferences and to obtain high-accuracy determination results [8].…”

In this work, amphiphilic polymers synthesized from carboxylated carbon nanotubes stabilized high internal phase emulsions are demonstrated to be capable of direct extracting zearalenone and zearalanone in samples consisting of an oil‐water emulsion system. Under optimal conditions, the maximum adsorption capacities for zearalenone and zearalanone are 17.27 and 13.26 mg/g. The adsorption is mainly attributed to π‐π interaction, hydrophobic interaction, and hydrogen‐bonding interaction for zearalenone and zearalanone. The adsorption isotherms reveal that the adsorption of zearalenone and zearalanone on amphiphilic polymers synthesized from carboxylated carbon nanotubes stabilized high internal phase emulsions follows Freundlich model with multilayer and heterogeneous adsorption due to the presence of multiple kinds of adsorption sites. The relative recoveries of the spiked zearalenone and zearalanone in corn juice samples range from 85% to 93% with relative standard deviations lower than 3.52%. The results manifest the high efficiency of amphiphilic polymers synthesized from carboxylated carbon nanotubes stabilized high internal phase emulsions for the adsorption and separation of analytes in the oil‐water emulsion system. This study provides a new perspective on adsorbent engineering for the adsorption application in heterogeneous media.
