Research Interests

Our group studies on analytical chemistry and environmental chemistry.
Analytical separation and determination in aquatic media, replacing standard analysis methods with harmful reagents to non-harmful analysis procedure, development of analysis methods with less consumptions of energy and resources, analysis of physicochemical property of substances by analytical instruments including electrophoretic and chromatographic separation, and development of analysis method with surfactant micelles as hydrophobic partition media are the typical ones.
