Determination of Critical Micelle Concentration of Sodium Dodecyl Sulfate in Magnrtic Water Medium by Electrical Conductivity

Abstract

Anionic surfactant was investigated in magnetic water medium using conductometric technique. The critical micelle concentration (CMC) was determined both in absence and presence of different concentration percentages of short alcohol chains in a temperature range (293.15–308.15K). The thermodynamic parameters (∆Gᵒm, ∆Hᵒm, ∆Sᵒm) were calculated and discussed.
