Abstract
With the continuous progress of science and technology and the rapid development of industrial production, the separation and purification of me tal ions plays a vital role in many fields such as mining, me tallurgy, chemical industry and environmental protection. Although traditional extractants have achieved some success in me tal ion separation, they often have problems such as low selectivity, poor stability and low environmental friendliness. Therefore, the development of new extractants to improve the efficiency and performance of me tal ion separation has become one of the current research hotspots. This paper focuses on the application and performance research of new extractant in me tal ion separation, aiming to realize efficient and accurate separation of me tal ions by designing and synthesizing new extractant with specific structure and function. Firstly, the current research status and development trend in the field of me tal ion separation were reviewed, and the advantages and disadvantages of traditional extractants and the significance of new extractants were analyzed. Then, the design idea, synthesis method and structure characteristics of new extractant are introduced in detail, including organic extractant, inorganic extractant and compound extractant. These new extractants significantly improve the selectivity, affinity and stability of me tal ions by introducing specific functional groups, adjusting the molecular structure or optimizing the coordination environment. In the aspect of performance research, the performance of the new extractant in me tal ion separation was evaluated by various experimental methods. The experimental results show that the new extractant has excellent performance in me tal ion separation, such as high selectivity, high extraction rate and low energy consumption. At the same time, the influence of extraction conditions (such as pH value, temperature, extractant concentration, etc.) on extraction performance was also discussed, which provided a valuable reference for practical application. The application potential of the new extractant in environmental protection is also discussed. With the increasing awareness of environmental protection, how to effectively remove heavy me tal ions in wastewater has become an urgent problem to be solved. Because of its high efficiency and environmental protection, the new extractant has shown a broad application prospect in the field of heavy me tal ion removal. In this paper, the application and properties of new extractant in me tal ion separation are studied systematically, which provides a new idea and method for the development of me tal ion separation technology. In the future, with the continuous development and optimization of new extractants, it is believed that it will play a more important role in the field of me tal ion separation and environmental protection.
