Abstract
In this paper, the application of new adsorbent materials in the treatment of heavy me tal wastewater and its challenges are discussed. Firstly, the preparation technology and characterization technology of the new adsorbent were summarized, and the adsorption mechanism of the new adsorbent was analyzed. With its unique structure and properties, new adsorbent materials show great potential in the treatment of heavy me tal wastewater. However, in practical applications, the new adsorption materials also face some challenges. On the one hand, its adsorption capacity is limited, which is difficult to meet the needs of large-scale wastewater treatment; On the other hand, the selectivity is poor and it is difficult to efficiently remove specific heavy me tal ions. In addition, the insufficient regeneration and recycling performance of the material, as well as the weak anti-interference ability, also limits its application in complex wastewater environments. To solve these problems, this paper puts forward the corresponding optimization strategy. Firstly, the adsorption capacity of the new adsorption material can be effectively improved by increasing the pore structure, optimizing the adsorption area and enhancing the binding capacity by using functional modification. Secondly, through the design and introduction of selective functional groups, the application of molecular recognition technology and the regulation of surface charge, the selectivity of the new adsorption materials can be significantly enhanced. Thirdly, the design of efficient regeneration process, the development of new regeneration agents and the use of biodegradation or photocatalysis technology can significantly improve the regeneration and recycling performance of new adsorption materials. Finally, the anti-interference ability of the new adsorbent can be improved by enhancing the anti-coadsorption ability, designing the adsorbent material to resist the interference of organic matter and optimizing the pH stability.
