| dc.description | AbstractAdsorption/desorption of toluene on montmorillonite, illite, and kaolinite was studied using the batch equilibrium method. The isotherms measured fit the Freundlich equation (r<sup>2</sup> >0.95). Montmorillonite adsorbed more toluene than illite or kaolinite; the adsorption of toluene on illite and kaolinite was not significantly different. Adsorption of toluene by montmorillonite showed an exponential increase as the ratio of toluene to clay was increased from 5 to 100. The rate studies showed that 62% of the adsorption was completed within 6 h. A rapid desorption was observed initially, followed by slow desorption after 1 h. The desorption rate decreased as the time of adsorption was increased. Almost all of the adsorbed toluene was extracted with water from the clay when the adsorption time was 0.1 h, but only 61% of the toluene could be desorbed when the adsorption time was 24 h. |
