Progress on Methods for Measuring Surface Tension of Liquids

Surface tension,one of the key influence factors to the mass transfer and reaction of multiphase system,is an important physical property of liquid.The basic principle,advantage,disadvantage and the improvement for measuring liquid surface tension with different methods were described.The methods were capillary rise method,Wilhelmy plate method,pendent drop method,drop volume method,maximum bubble pressure method.The problems in the surface tension measurement of wide temperature and pressure range,the chosen of experimental methods and the development tendency of these were introduced especially in this paper.
