| Outline of Final Research Achievements |
To separate and recover harmful or useful ionic substances in wastewater under mild condition, several easily hydrolysable surfactants were synthesized and applied to solvent extractant, coagulant, and adsorbent. The solvent extractions of ionic dyes, capable of repeated use of non-halogenated organic solvent and selective separation of mixed substrates, were performed. We also demonstrated that the particles dispersed with the surfactant and the surfactant-modified clays function as coagulant and adsorbent, respectively, leading to easy recovery of anionic dyes.
