摘要

Abstract

In order to determine the low interfacial tension

a spinning drop interfacial tensiometer was constructed.The apparatus was calibrated by measuring the interfacial tension of some low molecular weight systems and polyethylene glycol /dextran aqueous two-phase systems

with the determination error of 3.The interfacial tensions of PEG1000/Na2SO4

PEG/MgSO4 and PEG1000/(NH4)2SO4 aqueous two-phase systems Were determined.It is found that the salt type has strong effect on the interfacial tension.
