MAKROFOL KG MICROFILTERS WITH LARGE PORES APPLIED FOR THE SEPARATION OF 2 DIFFERENT LIQUID-PHASES (EMULSION)

Makrofol KG nuclear track microfilters have been successfully applied to separate two different and strongly mixed liquid phases (emulsion). The organic and the inorganic phase of the two emulsions used in this work were: (a) 48% tributyl phosphate (TBP) in kerosene and 2 N HNO3 and (b) 48% TBP in kerosene and 13 N HNO3, respectively. Makrofol KG f ilters having pore sizes k in the interval of 2.3 less than or equal t o k less than or equal to 8.0 mu m were used to get under some well de fined conditions a complete extraction of the organic phase out of the first emulsion (a), and filters with a range of pore sizes k of 5.5 l ess than or equal to k less than or equal to 10.5 mu m were employed t o obtain a complete separation of the organic part of the second emuls ion (b).
