摘要:

Radiolysis of aqueous solution of tri- and tetravalent cerium-nitrilo-tri-acetate complexes were studied both in the presence and in the absence of oxygen. A radiolytic mechanism has been proposed and discussed in which it is shown that the radiolytic degradation of the chelate is due to the OH radical, while radiolytic oxidation of trivalent cerium chelate to tetravalent cerium chelate, at alkaline pH, is due to hydrogen peroxide.
