新型汞离子吸附材料研究进展

Mercury pollution has a wide range of sources and emissions and has become one of the ten most serious pollution sources in the world because of extensive source and massive emission. Among the many mercury ion removal technologies, adsorption has evolved into a more sophisticated and extensively adopted processing technology because of its high efficiency and low cost. The key to adsorption is the adsorbent with excellent performance, while the adsorption performance of traditional adsorption materials is limited. Based on this, this paper summarized the novel adsorption materials for mercury ion in recent years, such as metal-organic frameworks (MOFs), covalent organic frameworks (COFs), conjugated microporous polymers (CMPs), conductive polymers, MXenes and composite materials. The relationship between the structural characteristics of these materials and their adsorption properties for mercury ions was discussed in detail. The prospect of mercury ion adsorption materials in water was summarized. It was pointed out that adjusting the structure of the material and adding specific functional groups were the directions for further research and development of new materials. It was hoped that this paper can provided some reference and inspiration for the design and development of the research of novel adsorption materials for mercury ion.
