Abstract

The modification by cationic surfactants of sorbents based on hydromica and kaolinite – layered silicates with rigid structural cell – was performed by a modified sol-gel method. It was shown that the modification leads to sharp decrease of the minerals hydrophilicity, and to the increase of their affinity to the molecules of anionic and non-ionic surfactants. Significant increase of the sorption capacity of modified minerals with respect to non-ionic surfactants was ascribed to the formation of bulk associates of cationic and non-ionic surfactants.
