Preparation method of CeO2 and CuO loaded ammonia-free system activated carbon

The invention discloses a preparation method of CeO2 and CuO loaded ammonia-free system active carbon, and relates to the technical field of adsorption material preparation, and the preparation method comprises the following steps: a, measuring the water capacity of to-be-impregnated active carbon, calculating to obtain the dosage of deionized water, based on the amount of the active carbon, taking 1-10% by weight of soluble cerium salt and 20-50% by weight of soluble copper salt, and uniformly mixing the soluble cerium salt and the soluble copper salt; dissolving in deionized water, heating, stirring and dissolving, and mixing to prepare an impregnation liquid; b, adding activated carbon to be impregnated into the impregnation liquid, uniformly stirring and mixing, and standing and calcining after sufficient impregnation to obtain a sample I; and c, preparing a non-ammoniacal alkali solution with the weight content of 10-30%, adding the sample I obtained in the step b, uniformly stirring and mixing, standing
