| Abstract: | Quinoline adsorption onto Ca-montmorillonite was studied as a function of quinoline and clay concentrations. At constant quinoline concentration, the adsorption decreased as the clay concentration increased in the suspensions. This decrease was attributed to the increase in calcium concentration in solution, associated with the increase in clay concentration, and its effect on the Ca-quinoline exchange equilibria. The results were described by a Langmuir type adsorption equation expanded to cover exchange sorption of cation quinoline. |
