摘要:
The solvent sublation technique, one of adsorption bubble separation techniques, is initially proposed by Sebba[1] as an option for ion flotation, in which the material adsorbed on the surface of ascending bubbles and then collected by a solvent in the column upper zone. The technique has advantage over ion flotation or solvent extraction:the possibility of easy handling of large volumes of aqueous samples; not limited by the equilibrium constant; the recovery of trace elements can eventually reach 100%; no emulsions formed; independent on the organic to aqueous phase volume ratio. So it has attracted many attentions in the removing trace levels of nonvolatile and volatile organic compounds from wastewater and the recovery of many metals[2,3]. But the studies on the mechanism of the process are very few[4],which is very important to the better application. So, in the paper, we investigated on the kinetics and thermodynamics of solvent sublation of Bromophenol blue-hexadecyl-pyridiumchlorid and compared the efficiencies of solvent sublation with conventional separation methods.
