Abstract

In this paper, the demulsification has been achieved with the use of freeze/thaw (F/T) method and microwave radiation (MWR). The object of investigation were emulsion samples prepared by mixing the metal-working-oil, FESOL 09, produced by FAM, Krusevac, Serbia, and deionized water. F/T method has been successfully applied for the removal of oil from emulsions in our previous work. In this work, MWR has been additionally used for separation and enhanced heating of emulsion samples. The efficiency of oil removal has been improved with the assistance of MWR, up to 90%.
