Rapid Critical Micelle Concentration (CMC) Determination Using Fluorescence Polarization Analysis of the Physical-Chemical Properties of Detergents

ثبت نشده
چکیده

Surfactants are amphiphilic compounds that have a molecular structure containing both a hydrophilic (water loving) and a hydrophobic (water hating) region. The hydrophobic region is usually a long chain aliphatic hydrocarbon, whereas the hydrophilic portion can be composed of an ionic or non-ionic polar group. The physical nature of these molecules bestows the ability to reduce surface tension of solutions and to self aggregate into colloids known as micelles.

Salinity Effect on the Surfactant Critical Micelle Concentration through Surface Tension Measurement

One of the tertiary methods for enhanced oil recovery (EOR) is the injection of chemicals into oil reservoirs, and surface active agents (surfactants) are among the most used chemicals. Surfactants lead to increased oil production by decreasing interfacial tension (IFT) between oil and the injected water and to the wettability alteration of the oil reservoir rock. Since surfactants are predomin...

Experimental Study of Salinity and Ionic Strength Effects on Critical Micelle Concentration of a Cationic Surfactant (HTAB)

The interfacial tension of surfactant solutions is decreased with increasing surfactant concentration to obtain the critical micelle concentration (CMC). After that, the CMC values does not alter much. So this concentration is a critical point during surfactant flooding that is one of the chemical EOR techniques. The reduction of the CMC value is taken into consideration, since the surfactant f...

بررسی ویژگیهای سطحی و رفتار خوردگی نانوساختارهای نیکل ساخته شده در حضور سورفکتانت های مختلف

In this work, Ni nano structures with different surface morphology have been electrodeposited from the Waths bath using direct current (DC) and pulsed reverse current (PRC) techniques in the presence of three types of surfactants. CTAB, SDS, and Triton x-100 have been used as cathionic, anionic and nonionic surfactants respectively. The surfactants concentration have been selected at below, equ...

Micelle Formation in Sodium Dodecyl Sulfate and Dodecyltrimethylammonium Bromide at Different Temperatures

In an aqueous medium, both pure and mixed surfactants form micelles after reaching a concentration called the critical micellar concentration (CMC), whose determination has considerable practical importance normally to understand the self-organizing behaviors of surfactants in exact and detailed ways. Many studies have been devoted to the elucidation of micellar structures under different condi...
