Method for extracting technetium from molybdenum solution by means of activated carbon materials

The invention belongs to the field of radioactive nuclide separation, and particularly relates to a method for extracting technetium from a molybdenum solution by means of activated carbon materials. The method comprises the following steps that 1, a molybdenum and technetium mixed solution with the hydroxide ion concentration larger than or equal to 1 mol/L is prepared; 2, technetium in the molybdenum and technetium mixed solution obtained in the first step is adsorbed through the activated carbon materials; 3, a small amount of technetium which adheres to the surfaces of the activated carbon materials is washed with a washing solution; and 4, technetium adsorbed to the surfaces of the activated carbon materials is desorbed with a leaching solution with the hydroxide ion concentration smaller than 1 mol/L. The method has the advantages that the solid-phase separation material is good in radiation-resistant performance, stable in adsorption and separation performance, low in price and easy to obtain. 本发明属于放射性
