The invention discloses a method for preparing a chlorine adsorption material for use in waste incineration and application of the chlorine adsorption material. The chlorine adsorption material adsorptive for chlorine-based substances during the waste incineration is prepared by mixing raw materials which include natural iron ores and quartz stones, and modifying the iron ores and the quartz stones with CaO through an ultrasonic impregnation method. The prepared chlorine adsorption material has a large pore size, a high porosity and a stable structure, and shows higher adsorption efficiency and adsorption capacity for the chlorine-based substances during the waste incineration. The use of the low-cost natural iron ores and quartz stones can reduce the cost in processing the chlorine-based substances, make great use of resources and facilitate environment protection.
