| Research Abstract |
Because of scientific significance of characterization of materials and speciation of trace elements in environmental materials intensive development of separation-speciation chemistry and related highly sensitive analytical techniques have been jointly investigated by fifteen-five scientific members.In order to achieve the goal five themes have been attacked. 1 Highly sensitive preconcentration-fluorophotometry,FIA combined with catalytic reaction,palladium-enhanced GFAAS for volatile trace metals and a new trace characterization method based on thermoluminescence color image photography have been developed. 2 Synthesis of metal specific resins,chelating resins,new ligands and macrocyclic and pseudo-macrocyclic extractants and their evaluation from the view points of trace characterization have been worked out. 3 Novel extraction system for rhodium,and new approach on the design of extractive separation scheme based on the HSAB rule are established.Fundamental approach for exploring the possible separation of metalhalogenocomplexes in ion association systems allows to develop highly selective separation and photometric quantitation techniques. 4 Dynamic ion-exchange separation of adjacent rare earths, preconcentration of trace metal complexes on poly[chlorotrifluoroethylene]resin, and heavy metal speciation in fresh waters with solid absorbents are also accomplished. 5 On-line preconcentration and separation methods are developed for the determination of traces by atomic/molecular spectrometry.
