Preparation method of carbon nanotube adsorbent with metal ferrocyanide having a selective adsorption property to cesium or strontium adsorbent prepared by the method and seperation method of cesium or strontium using the adsorbent
The present invention relates to a method for producing a carbon nanotube in which ferrocyanide metal is immobilized and a ferrocyanide metal is immobilized with a magnetite, and a cesium or strontium adsorbent.More specifically, carbon nanotubes are reacted with an acid solution, surface oxidized, and reacted with EDA and DCC to introduce an amine group on the surface, react with a divalent metal-containing compound, and react with a ferrocene-containing compound, The present invention also relates to a method for producing a fixed carbon nanotube, which comprises reacting carbon nanotubes with an acid solution to oxidize the surface of the carbon nanotube, and then reacting the carbon nanotubes with divalent and trivalent iron ions to fix the magnetite on the surface, And a method for producing a carbon nanotube into which a ferrocyanide metal is introduced by reacting with a divalent metal-containing compound.The adsorbent containing carbon nanotubes in which the ferrocyanide metal is immobilized and the magnetite is immobilized and the ferrocyanide metal is introduced exhibits selective adsorption ability to cesium or strontium in the radionuclide.
