Material Capture in the Surfactant Solid State

Abstract

An interesting behavior of gaseous capture of materials by solid surfactant matrices was examined in comparison with behaviors of other substances (other matrices) which possess long alkyl chain and supposedly similar crystal structure to the surfactant. Through this study it was revealed that the behavior of gaseous capture of materials was characteristic to the surfactant species. Of all surfactants cationic species was conspicuous followed by nonionics, while in anionics the behavior was very poor. Among cationics quaternary and tertiary species especially superior to any other class. For these cationic surfactant species the powder X-ray diffraction measurement disclosed that the gaseous capture of materials remarkably modified matrix surfactant crystal lattices, causing the surfactant molecular complex formation which had already been established by authors.
