Electroflotation of chlorinated organic compounds from wastewater using a soluble aluminum electrode was examined in the presence of surfactant added as a collector. The effects of the kind and concentration of surfactant, power consumption, and pH on removal of 2,4,5 trichlorophenoxyacetate (2, 4,5-T) and 2,4,6 trichlorophenol (2,4,6 TCP) were examined experimentally. Cationic surfactants such as cetyltrimethylammonium bromide and trimethylstearyl ammonium chloride were shown to be effective to remove chlorinated organic compound. The final fraction of cationic surfactants remaining decreased below about 5 percent. The kinetics of flotation observed experimentally to follow a first-order rate equation. As the concentration of cationic surfactants increased, the kinetic constant increased and the final fraction of chlorinated organic compounds remaining decreased. The kinetic constant increased with increasing power consumption, and reached a maximum value at approximately pH 9.
