Application of different classes of surfactants is increasing nowadays in a number of technological areas. The main areas are (1) biotechnology, (2) electronic printing, (3) high technology electronic ceramics, (4) magnetic recording, (5) microelectronics, (6) nonconventional energy production, (7) novel pollution control, and (8) novel separation techniques. Among them, use of surfactant in separation processes is a major area of research in surfactant and separations science. Surfactantbased separations have a number of potential advantages over traditional methods. They often are low-energy intensive processes because large temperature or phase changes are not needed for separations. At times, surfactants offer improved selectivity over a conventional solvent system. An additional advantage of micellar systems is that they are compatible with electrochemical detection while conventional organic solvents are not. Surfactants are often environmentally innocuous and of low toxicity, so the leakage of a small amount of surfactant into an aqueous process stream from the separation may be tolerable, in contrast to toxic solvents from liquid-liquid extraction. Surfactant-based separation of toxic chemicals is often getting attractive nowadays.
