Effect of heat treatment on efficacy of Thai bentonite for adsorption of aflatoxin B1 in vitro
This research evaluated the effects of heat treatments on the efficacy of Thai bentonite (TBN) for adsorption of aflatoxin B1 (AfB1) in vitro. The TBN clays were ground to sizes less than 40, 60, 100 and 200 μm and heated for 1 hour at eleven heating temperatures at 25°C and from 100°C to 1000°C, at...
