Research Clusters

Separation, Synthesis, and Detection by Means of Ionic Solutes Handling

Research Keyword: Ionic solute, Sea water, Metal ions, Separation, Detection

In this research cluster, we targeted ionic solutes. Ionic solutes are important player in environment, and human body. The development of ionic solutes analysis methods which can detect ultra-trace levels, and/or in complex matrices are developed. Furthermore, the developed methods can be applied real samples such as soil extract, sea/river waters, industrial products and human fluidics. Recently, we have also succeeded to develop the methods for highly pure ionic liquid synthesis and radio-active metal separation/purification.
