Abstract
Thimerosal is removed from aqueous effluent streams from vaccine production to provide an invironmentally-acceptable effluent stream. The thimerosal first is converted to ionic form by chlorination, the resulting solution is dechlorinated to remove dissolved unreacted chlorine, and then the ionic mercury is removed by ion-exchange employing thiol groups.
