Straining flow of a micellar surfactant solution

Straining flow of a micellar surfactant solution

We present a mathematical model describing the distribution of monomer and micel-lar surfactant in a steady straining flow beneath a fixed free surface. The model includes adsorption of monomer surfactant at the surface and a single-step reaction whereby n monomer molecules combine to form each micelle. The equations are analysed asymptot-ically and numerically and the results are compared with...

Spectrofluorimetric study of 1-naphthoic acid in micellar surfactant solution

This study focuses on the spectrofluorimetric behaviour of a pharmaceutically and analytically important molecule 1-naphthoic acid in the presence of various surfactant solutions. Micellar solubilization is a powerful alternative for dissolving hydrophobic compounds in aqueous environment. Fluorescence and absorption spectroscopy are the two techniques used to monitor the micellar solubilizatio...

Kinetics of nonionic surfactant adsorption at a fluid-fluid interface from a micellar solution.

FLUORESCENCE SPECTRAL STUDY OF THE SOLUBILIZATION OF BENZO [a] PYRENE IN MICELLAR SURFACTANT SOLUTION

Benzo[a]pyrene is one of a group of chemicals called polycyclic aromatic hydrocarbon, PAHs for short, and found in cigarette smoke, in the exhaust from automobiles and coal tar. Polycyclic aromatic hydrocarbons (PAHs) are toxic environmental pollutants that are known or suspected carcinogens or mutagens. Bioremediation has been used as a general way to eliminate them from the contaminated sites...

The wormlike micellar solution made of a zwitterionic surfactant (TDPS), an anionic surfactant (SDS), and brine in the semidilute regime.

Structural and dynamical properties of a micellar solution are studied mainly through examining its rheological behavior in the semidilute regime. The micellar solution is made of a zwitterionic surfactant N-tetradecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate, sodium dodecyl sulfate, and salty water. In particular, we are interested in how the system is affected when the ionic strength of the ...
