Abstract
A correlation is established between aflatoxin B1 binding on raw montmorillonite clays and the ratio of their surface acidities divided by their porosities for surface acid sites whose pKa values fall in the range 5.0-6.8 (i.e. weakly acidic) and porosities for pores whose diameters fall in the region 50-600 A. This information provides a method for preselecting clay additives for animal feeds which have enhanced toxin binding capacity.
