Naphthalene Sorption on HPTMA-Modified Clays
초록
Clays coated with cationic surfactants (organoclays) have been investigated due to their effectiveness in sorbing organic compounds from water The objectives of this study were to (1) study the sorption characteristics or a cationic surfactant (HDTMA) to clay minerals; (2) examine the partitioning of HOC (naphthalene) to the adsorbed surfactants within the context of the first objective, and (3) develop overall HOC distribution coefficients that consider sorbed surfactant amounts. The sorption of hydrophobic organic contaminant was due to partitioning of the organics into the organic pseudophase created by the surfactant tail groups. Sorption of naphthalene by HDTMA-clays at different surfactant surface coverages revealed that the naphthalene K
