Abstract
PURPOSE:To obtain a treatment method which is capable of yielding technetium directly in a solid state by bringing a gas contg. the technetium into contact with active carbon or aq. active carbon soln. CONSTITUTION:The gas contg. the technetium is brought into contact with the active carbon or the aq. active carbon soln. As a result, the technetium is adsorbed and solidified to the active carbon by the sorption effect of the active carbon. The active carbon to be used is exemplified by ordinary active carbon prepd. by carbonizing carbon stock such as coconut shells, coal or timber then activating the same with steam or chemicals such as zinc chloride. The active carbon in both granular and powder states is usable.
