Wu Youting, Mei Lehe, Zhu Ziqiang, et al. CONSTRUCTION OF SPINNING DROP TENSIOMETER AND DETERMINATION OF LIQUID-LIQUID INTERFACIAL TENSION[J]. CIESC Journal, 1996, (4).DOI:
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.
