THE EFFECT OF RADIATION AND METAL-ION ADDITION ON THE CO2 REDUCING REACTION IN IRON-CONTAINING WATER

The effect of gamma-rays and metal ion additives has been studied usin g solutions suspended with iron powder and saturated with CO2. It is p roved that the products are H-2, CO and seven hydrocarbons composed of less than 4 carbon atoms, and that CO is formed only under irradiatio n, unlike other products. Without gamma-rays, the yield is significant ly reduced by introducing metal ions, whereas an increased yield is co nfirmed under exposure. The result is understood by taking into accoun t the reduction of redox potential.
