Selective mycotoxines sorbent based on molecular imprinted polyaniline structures

Abstract

The constant increase in contamination of agricultural products with mycotoxins makes it urgent to develop new methods for their sorption, isolation, and determination. Molecular imprinting is a promising method for recognizing and isolating target molecules based on specifi c sorption mechanism. The work considers the possibility of obtaining and practical use of mycotoxin–specifi c selective sorbents based on imprinted polyaniline structures using a structural analogue of the mycotoxin zearalenone – 4-hydroxycoumarin. The optimal carrier for the synthesis of molecularly imprinted polymers has been selected. The specifi city of 4-hydroxycoumarin sorption from model solutions has been studied. The practical possibility of sorption and extraction of ZEA from an artifi cially contaminated wheat extract has been demonstrated.
