The foam fractionation of zinc ion from dilute aqueous solution with sodium dodecylbenzene sulfonate (NaDBS) as collector was studied using a single stage foam apparatus. Results are expressed as the surface excess and distribution factor of zinc. The optimum pH for the removal of zinc was found to be from 3.0 to 5.0. Efficient removal of zinc (high distribution factor) took place at low zinc ion concentration (less than 5 ppm) and low collector concentration consistent with a stable foam. The order of effectiveness in the removal of zinc by various forms of collector was found to be KDBS < NaDBS < LiDBS < HDBS.
