Study of conductivity and CMC of sodium decyl sulfate in (alkanol+ aqueous) Systems at different temperature

Author Name : Dr. Mayank

ABSTRACT

Diversified uses of surface active agents depend on their tendency to aggregate in a particular solvent. The aggregation of monomers of surface active agents in some solvents forms particles of colloidal dimensions, called micelles. The concentration at which the micelle formation takes place is called critical micelle concentration (CMC).In order to understand the colloidal behaviour of anionic surfactants in mixed solvents, a systematic study on the conductance of sodium decyl sulfate in aqueous and alkanols have been made with a view to determine whether or not the micellar aggregates are formed for such systems.CMC are determined, if any by the graphs  and investigate the validity of various equations in these systems.

Key Words: sodium decyl sulfate, CMC, Micelles, conductivity, anionic surfactants, alcohol-water system.
