Removal of cationic surfactants from water using clinoptilolite zeolite
Batch and column experiments were conducted to evaluate the efficiency of a clinoptilolite zeolite as an inexpensive sorbent material to remove cationic surfactant from water. With an initial surfactant concentration greater than its critical micelle concentration, the removal of surfactant is achieved by admicellar sorption onto the zeolite surface. Although the sorption capacity of hexadecylt...
متن کاملNew research progress of the demulsification of produced liquid by polymer flooding
Polymer relies on its special properties, which is an effective means to enhance oil recovery. But the composition of its produced liquid is very complex, especially emulsifying phenomenon severely constrains the process oil-water separation at a later stage. At present technical means of demulsification taken by both home and abroad oilfield mainly include physics, chemistry and other methods....
متن کاملMixed micelles of cationic surfactants and sodium cholate in water.
Critical micelle concentrations (CMCs) of cationic surfactant (alkyltrimethylammonium bromides, CnTABr, where n = 10, 12, 14, 16 and 18), and a bile salt sodium cholate (NaC) were determined from surface tension, conductance and dye solubilization methods, while of their equimolar mixtures from surface tension and dye solubilization methods. The interaction parameter (beta) obtained from analys...
متن کاملThermodynamic Analysis for Cationic Surfactants Binding to Bovine Serum Albumin
In the present study, the binding isotherms for interaction of a homologous series of n-alkyltrimethyl ammonium bromides with bovine serum albumin (BSA) have been analyzed on basis of intrinsic thermodynamic quantities. In this regards, the intrinsic Gibbs free energy of binding, AGb(i,)„ has been estimated at various surfactant concentrations and its trend of variation for both binding sets ha...
متن کاملFabrication of vesicles from mixed cationic/anionic surfactants with additives
In this study, positively charged catanionic vesicles were fabricated from an ion pair amphiphile (IPA), hexadecyltrimethylammonium-dodecylsulfate (HTMA-DS), with the addition of a double-chained cationic surfactant, ditetradecyldimethylammonium bromide (DTDAB), and cholesterol by a mechanical dispersion process. The effects of the added cholesterol on physical stability of the catanionic vesic...
