Solvent Extraction Chemistry

Freiser教授和他的学生将研究液-液溶剂萃取金属的基本过程。本项目属于分析化学和表面化学领域，将涉及溶剂萃取机理的动力学和热力学研究。光谱结构探针将用于研究液-液界面在溶剂萃取分离中的确切作用。本研究的结果将用于优化提取方案，并为分析样品中金属化合物的分离和提取开发新的分析方法。这个项目包括对金属离子螯合物的液液萃取的基本机制进行广泛的研究。这种研究特别重要，因为液-液溶剂萃取是分离和回收重金属的重要商业技术。这项研究的结果将有助于阐明类似过程的机制，如液体分配和胶束色谱，膜基离子选择电极反应和生物膜中的运输过程。

Professor Freiser and his students will investigate the fundamental processes involved in liquid-liquid solvent extraction of metal species. This project in the area of Analytical and Surface Chemistry will involve kinetic and thermodynamic studies of solvent extraction mechanisms. Spectroscopic structural probes will be used to study the exact role of the liquid-liquid interface in solvent extraction separations. The results obtained from this investigation will be used to optimize extraction schemes as well as develop new analytical methods for the separation and extraction of metal compounds from analytical samples. %%% This project involves an extensive investigation of the fundamental mechanisms governing the liquid-liquid extraction of metals as metal ion chelate complexes. Such investigations are particularly significant because liquid-liquid solvent extraction is a commercially important technique for the separation and recovery of heavy metals. The results of this investigation will help to elucidate the mechanisms of similar processes such as liquid partition and micellar chromatography, membrane-based ion selective electrode responses and transport processes in biomembranes.
