“…The type of exchangeable cation in the montmorillonite film significantly affects the desorption rates of TMSO, similar to TMSOz (Lorprayoon and Condrate, 1981). After heat treatment at 150~ for one day, the IR spectra of the TMSO-treated samples of Na-, H-, and natural montmorillonites indicate lower sulfur contents and lower intensities of the TMSO bands than those of transition metal-montmorillonites (see Figure 1).…”

“…For example, a very strong band at -1292 cm -a due to the antisymmetric O=S=O stretching mode of sulfolane (TMSO0 did not increase in intensity during the treatment. Lorprayoon and Condrate (1981) noted this strong band when montmorillonites were treated with TMSO.,. The intensities of the bands for TMS-treated H-, Na-, and natural montmorillonites associated with TMS or TMSO decreased more rapidly than those of treated transition metal-montmoriltonites when the samples were heated for one day at 150~ indicating that TMS and TMSO molecules were only physically adsorbed in the former clay films.…”
