Preparation method of normal-temperature renewable CNCL adsorption material

The invention relates to the field of adsorption material preparation, in particular to a preparation method of a normal-temperature renewable CNCL adsorption material. The preparation method comprises the following steps: dipping a zirconium hydroxide compound containing a polyhydroxy structure, sublimating with organic amine, drying, tabletting, crushing and screening. The material used in the invention can realize renewable adsorption of CNCL by using physical adsorption and weak chemical adsorption; the preparation method is green and energy-saving, the used process steps are simple, and the used materials are cheap; no other heavy metal pollutants are introduced in the preparation process of the adsorbent provided by the invention, the technology is simple, the adsorbent can be regenerated and desorbed for five times under the normal temperature condition, and a technical support can be provided for the design of a normal-temperature renewable CNCL device. 本发明涉及吸附材料制备领域，具体涉及一种常温可再生吸附CNCL材料的制备方法；通过将含多羟基结构
