In this study bentonite was modified with two chitosans, commercial or chitosan synthesized from mushroom. Obtained
products were subsequently treated with hexadecyltrimethyl ammonium bromide in the amount of 50% of the bentonite`s
CEC value. Starting material and all prepared composites were characterized by FTIR-ATR spectroscopy in order to
confirm modification with organic molecules. Adsorption of zearalenone (ZEN) by clay-chitosan composites and claychitosan-surfactant composites was investigated at pH 3. Results showed that adsorption of ZEN was higher for
composites that had both chitosan and surfactant, confirming that surfactant ions are responsible for ZEN adsorption.
Additionally, the effect of adsorbent mass on ZEN adsorption was investigated for clay-chitosan-surfactant composites
(pH 3) and results have shown that adsorption increased with increasing the amount of both composites.
