In this study three bentonite clays (bentonite from deposit Beretnica in Republic of Serbia, commercial bentonite and gray
clay from Šipovo deposit in Bosnia and Herzegovina) were investigated as adsorbents of aflatoxin B1 (AFB1). In a single
in vitro AFB1 adsorption experiment, all three bentonites showed high adsorption efficiency for AFB1 at pH 5. The effect
of adsorbent mass on AFB1 adsorption was also studied, with the same initial AFB1 concentration, at pH 3, and it was
shown that toxin adsorption decreased with decreasing amount of each bentonite in suspension. Thermal analysis was
performed in order to determine the structural differences between investigated bentonites. Results showed that gray clay
was trans-vacant bentonite while other two clays were cis-vacant bentonites. Aflatoxin B1 adsorption experiments, at pH
3, showed that trans-vacant gray bentonite had higher affinity for AFB1 than commercial cis-vacant bentonite. The
highest adsorption was achieved with cis...-vacant bentonite from Beretnica deposit.
