The equipment for the Bismuth-II process has been mounted and is ready for installation at Unit IV. The major portion of the gamma activity in the aluminum jackets is known to consist of iron and one of the following elements: zinc, cobalt, manganese, and nickel. Accordingly, a separation of these elements from aluminum should be obtained by precipitation from a concentrated sodium hydroxide solution to which sodium peroxide is added. Experiment showed that 88 per cent of the gamma activity was separated by this method. Experiments have been run on the equilibrium between postum ions, postum metal, arsenious acid, and arsenic metal in hydrochloric acid. From these preliminary results it is believed possible to accurately measure the potential of postum relative to arsenic. However, before the potential of postum can be determined, it will be necessary to obtain more accurate measurements on the potential of arsenic
