Method for preparing adsorption and degradation material from copper slag and hemp stalks and application of adsorption and degradation material

The invention discloses a method for preparing an adsorption and degradation material by using copper slag and hemp stalks, and particularly relates to a method for preparing an adsorption and degradation material by using copper slag and hemp stalks, which is characterized by comprising the following steps: reacting crushed copper slag with concentrated acid at 120-140 DEG C for 3-5 hours, carrying out solid-liquid separation, sufficiently mixing the solid with the crushed hemp stalks, and calcining in a nitrogen atmosphere to obtain the adsorption and degradation material. And cooling to obtain the adsorption and degradation material. The prepared adsorption and degradation material can efficiently remove sexavalent substances, the purposes of treating waste with waste and fully utilizing resources are achieved, and social benefits and economy are remarkable; the method has the characteristics of simple process, low cost, high resource utilization rate and no special requirement on equipment, and is suitabl
