| Abstract: | A zinc-exchanged montmorillonite (Zn-MONT) was prepared from a natural montmorillonite (MONT) and the adsorption of aflatoxin B1 (AFB1) was investigated at pH 3 and 7. Characterization of Zn-MONT was done by determination of chemical composition, the point of the zero charge (pHpzc), thermal (DTA/TGA/DTG) and X-ray powder diffraction (XRPD) analysis. |
