| Abstract: | In recent years, the use of synthetic surfactants, “detergents”, has brought about extensive foaming on rivers and during sewage treatment. Many methods have already been proposed on the removal of surfactants from waste water by the physico-chemical approach. The present paper however deals with the removal of the anionic surfactant, dodeclbenzensulfonate (DBSNa, M.W. = 348.48) form aqueous solution by the bubble separation technique, which has already been investigated in model systems by some workers.(1–10) This paper is also devoted in part to the removal of cationic metallic ion(12–17) from its dilute solution by suing a DBSNa collector in a stable foaming region, (pH = 6.3) similar treatments have employed the precipitate floatation mehtods.(18,19) |
