DETECTION OF GASEOUS PRODUCTS IN THE RADIOLYSIS OF AQUEOUS SOLUTIONS

Article abstract of DOI:10.1021/j100321a022

A new technique for the direct determination of radiolytically produced gaseous products is discussed.The method consists of continuously bubbling a gas through a sample cell and monitoring the effluent with a mass spectrometer.It has been applied to the determination of H2 and CO2 produced in various aqueous solutions irradiated with ⁶⁰Co γ radiation.The yield of H2 is found to be 0.51 molecules/100 eV in aerated ferrous sulfate solutions and in deaerated KBr solutions.The effect of saturating the ferrous sulfate solution with oxygen or addition of KNO2 to the KBr solution is the same with a yield of H2 of 0.43 molecules/100 eV.The yield of OH radicals as determined by the production of CO2 in dilute oxygen-saturated formic acid solutions is 2.5 molecules/100 eV.
