THE COMPOSITION AND STRUCTURE OF SODIUM DODECYL-SULFATE DODECANOL MIXTURES ADSORBED AT THE AIR-WATER-INTERFACE - A NEUTRON REFLECTION STUDY

Abstract:

Neutron reflection has been used to study the composition of layers of sodium dodecyl sulfate (SDS) and dodecanol mixtures adsorbed at the air/water interface. Saturation of the surface by dodecanol at a 6.7 mM SDS concentration occurs when the bulk dodecanol concentration is about four times the solubility of dodecanol in pure water, indicating that even below the cmc dodecanol is solubilized by SDS. At a fixed dodecanol/SDS ratio the adsorption of dodecanol passes through a maximum at about...
