A method and an apparatus are disclosed for desorbing TEDA by utilizing a fluidized bed so as to reuse a used impregnated active carbon for the purpose of removing toxic materials from a fluid. The impregnated active carbon is injected into a fluidized bed at a high temperature to carry out a desorbing process, in such a manner that TEDA and CH.sub.3 l are desorbed from the impregnated active carbon at a high temperature by utilizing the high volatility of TEDA and CH.sub.3 l. If a heated air is injected through an air inlet into the desorbing tower, the high temperature air and the used impregnated active carbon are met in a fluidized state, with the result that the active carbon with TEDA and CH.sub.3 l desorbed is discharged.
