It is understood that adsorption method is widely used as the core technology because of its remarkable effect, simple operation and low cost. Organic skeleton materials with valence of * * have the characteristics of large specific surface area, high porosity, high crystallinity and good stability, showing great potential in the field of pollutant adsorption and separation, and have become one of the frontier hotspots in the field of materials and environment in the world.
In this patent, a modified organic frame material with valence of * * * was prepared by radiation technology. By surface modification of the organic frame material with valence of * *, the adsorption capacity of heavy metal ions was improved by interaction between static electricity and heavy metal ions. The research results show that the modified material of this patent has a good adsorption effect on heavy metal ions, and can quickly adsorb a variety of heavy metal ions in a few minutes. The adopted irradiation method uses less chemical reagents, can be carried out at room temperature, avoids using a chemical reaction kettle, and is simple to operate, so it is a green and low-carbon preparation method. The invention can provide a new synthesis strategy for heavy metal adsorption materials and provide theoretical basis and technical support for the removal of heavy metal pollution. (Wang Yu)
