摘要：
This study showed that the efficiency of removal of sigma-dichlorobenzene from water by batch froth flotation increases as changes in salinity cause the system to vary from a Winsor Type I microemulsion to a Winsor Type III microemulsion. The cationic surfactant studied is more effective than either the monosulfate or the disulfonate anionic surfactants studied. The oil flotation efficiency increases as the initial surfactant concentration increases, as the salinity increases (causing a Winsor Type I to III transition for these systems), and as the oil/water ratio decreases.
