I. INTRODUCTION
For several years now surfactant molecules and their aggregates have been applied in various domains of separation science exploiting the peculiar properties of these microheterogeneous systems and the practical advantages that they can offer as alternative solvent systems. Surfactant-based separations play a significant role in important areas including analytical chemistry, industrial chemistry, biotechnology, and environmental remediation processes, where micellar solutions are at the basis of recent successful procedures applied to clean polluted water, soils, and sediments.
