A large number of chemicals have been used and detected in the environmental waters in Japan. To evaluate the pollution exactly, the development of analytical technique for the chemicats in water is important. Micellar electrokinetic chromatography (MEKC) is a new, high-performance analytical method and has a high separation efficiency. The author has carried out fundamental studies on the analysis of environmental pollutants by MEKC. First study is the investigation of the separation principle of MEKC. The distribution coefficients and thermodynamic parameters of the phthalate esters including priority pollutants in micellar solubilization were investigated. The separation mechanism in MEKC with or without added methanol was discussed. The influence of surfactant structures on the migration behavior of aromatic compounds was also investigated. We found three homologous sodium N-acyl sarcosinates and sodium N-lauroyl-N-methyl-β-alaninate were useful for MEKC. The polar moiety of surfactant is significant to change separation selectivity for hydrophilic solutes. The next study is the application of MEKC to the separation of environmental pollutants. Phthalate esters, pesticides for golf links, aniline derivatives and derivatized lower aliphatic aldehydes were successfully separated.
