Abstract
The formation mechanisms of hydrogen peroxide in titanium sulfate-oxalic acid system by the 60Co gamma-ray irradiation was investigated. The radiation yields of hydrogen peroxide formed were measured at titanium ion concentrations (1×10-3-1×10-2M) and oxalic acid concentrations (1×10-3-1×10-1M) in the 0.8N sulfuric acid solution. The results obtained were quantitatively consistent with a simple reaction schemes which allowed for the determination of hydrogen peroxide in the oxygen gas-saturated system. The over all of the measured hydrogen peroxide yields in this system are found that the recombination of OH radical in the spur and the radiolysis of oxalic acid are attributed.
