This report is an attempt to study adsorption and reduction of interfacial tension caused by adsorption of nonionic ethoxylated nonyl phenols in emulsion. In order to study these phenomenon a method for estimating adsorption and interfacial tension in emulsion was developed. It has been found, in contrast to a concept which appears in literature, that there is no correlation between values of interfacial tension as measured in emulsified and separated oil-water systems. Yet, there seems to be a significant correlation between adsorption values as measured in emulsified and separated oil-water systems. In addition it has been found that the values of maximum adsorption of the emulsifiers as measured in the separated oil-water system correlate linearly with HLB values of these emulsifiers. Such correlation may indicate possible dependance of HLB values on emulsifier's adsorption to the interface. |
