Abstract

The cloud point (CP) determination of non ionic surfactant in presence of additives is useful in the study of interaction between surfactant and additive. Polyoxyethylene (20) sorbitan mono-oleate (Tween 80) was used as surfactant and chlorides of some alkaline earth metals like magnesium, calcium, strontium and barium were used as additives. The addition of these additives in Tween 80 solution caused decrease in cloud point of the surfactant. The influence of alkaline earth metal salts on the cloud point of Tween 80 indicates that the clouding phenomenon results in merging of different micelle. The thermodynamic parameters of clouding process (&
