Light transmittance as a measure of interfacial area in liquid‐liquid dispersions

Abstract

Abstract Interfacial area in liquid‐liquid systems has been measured photographically. Precision and accuracy of the method have been shown to be better than 10%. To avoid tedium of counting drops, a simple light probe of easily reproducible design has been developed to measure the light transmission through the dispersions formed. A correlation of light transmittance with interfacial area is presented and its usefulness and limitations are discussed.
