Abstract
The influence of typical ·OH radical scavengers as potassium formate and isopropanol on the radiation-induced removal of lead was individually studied. The lead can be completely removed from aqueous solutions containing 1×10−2 mol/L of formate already at the dose of 2.5 kGy. With increasing concentration of formate (5×10−5–1×10−2 mol/L) increases the amount of Pb(formate)+ species in the solution before irradiation. The radiation product is metallic lead at low concentration of formate to PbCO3 at higher concentration of scavenger. In the system with 10% isopropanol dominates the species Pb2+ and the product of radiation reduction is then metallic lead.
