    Abstract

    Mycotoxins are secondary metabolites with a high toxicity produced by fungi and widely exist in feeding, thus reducing feed quality and affecting human-being and animal health. Montmorillonite as a feed additive can effectively reduce the risk of mycotoxin absorption by organisms, but its surface is highly hydrophilic, and the binding rate with weak/non-polar mycotoxins(such as OTA) is low. In this paper, OTA/montmorillonite composite adsorption material (i.e., CPC-MT) was prepared with pyridine salt CPC as a modifier. Its structure before and after montmorillonite modification was analyzed. The OTA adsorption behavior of modified montmorillonite was investigated through batch adsorption experiments combined with kinetic and isothermal adsorption models, so as to provide a technical scheme for effective adsorption of mycotoxins in feed.
