Surfactant-based separation techniques largely exploit the solubilizat
ion power of micelles and other amphiphilic aggregates towards a great
variety of hydrophilic and hydrophobic solutes. Micellar extraction,
based on the cloud-point phenomenon, and micellar ultrafiltration have
been successfully applied for preconcentration and removal of organic
and inorganic analytes of environmental concern from aqueous media. I
n particular, the recent development of chelating surfactant aggregate
s allows to perform very selective demetallation treatments. The facto
rs which control the separation efficiencies of these methods are exam
ined and discussed.
