Radiation removal of lead from aqueous solutions-effects of various sorbents and nitrous oxide

The influence of selected adsorbents (active carbon, bentonite and zeolite) on the radiation removal of lead from its aqueous solution using electron beam radiation was investigated. Both positive and negative effects on radiation reduction of Pb2+ ions depending on the dose applied were observed in presence of these solid modifiers. Besides deaeration with nitrogen, the efficiency of the process under study may be substantially increased by saturation of solution with nitrous oxide.
