The present invention provides a cleaning material and its preparation method and use. The preparation raw materials of the cleaning material include: a base material, a cross-linking agent and a functional group modified material; the base material includes sponge and/or cellulose aerogel. The cleaning material of the present invention is based on sponge and/or cellulose aerogel, and after modification with functional groups, the surface of the cleaning material has modified groups and has a large specific surface area, which can efficiently and specifically clean the target Metals, especially the radioactive metal substances on the surface of solid materials, can be directly wiped off, which has strong operability, and can realize the cleaning of solid surfaces and the recovery of heavy metals. In addition, the preparation method of the cleaning material of the present invention is simple, the cost is low, the regeneration method is simple, and can be recycled and reused repeatedly. |
