Natural zeolitic tuff was modified with 2, 5 and 10mmol M(+)/100g of octadecyldimethylbenzyl ammonium (ODMBA) ions and the products were denoted as OZ-2, OZ-5 and OZ-10. The starting material and organozeolites were characterized by determination of the point of zero charge (pH(pzc)) and by thermal analysis. In vitro sorption of fumonisin B(1) (FB(1)) was studied for all sorbents at pH 3, 7 and 9. The pH(pzc) for the zeolitic tuff was 6.8+/-0.1, while the pH(pzc) for OZ-2, OZ-5 and OZ-10 pH(pzc… CONTINUE READING
