Activated charcoal adsorbs aflatoxin B1

Activated charcoal was demonstrated to adsorb aflatoxin B1 in an efficient manner in vitro at a neutral pH. One mg aflatoxin was adsorbed by 100mg activated charcoal. The complex appeared to be quite stable. Destruction of the aflatoxin by alkaline conditions was confirmed, and a large measure of destruction was also noted at acid pH. Implications of the adsorption phenomenon include prevention of systemic absorption.
