Adsorption of cationic 1-hexadecylpyridinium bromide (HDPB) and non-ionic p-(1,1,3,3-tetramethylbutyl)-phenoxypolyoxyethylene glycols surf­ac­tants of the Triton X series (Triton X-45, Triton X-100 and Triton X-305) from their single and mixed aqueous sol... see more

The object of research is the reaction of phenol sulfomethylation in an aqueous medium, with the aim of obtaining water-soluble non-toxic products based on it used as surfactants. One of the most problematic places is the need to maintain the stability of... see more

It has been employed a mechanized procedure for the spectrophotometric determination of anionic surfactants in sea sand samples. The method is based on a batch leaching of surfactants from sand with two hot water successive treatments followed by on-line ... see more

The solvation-thermodynamic approach to study formation of electrical double layer of ionogenic surfactants micelles is proposed. The equations to estimate the Galvany potential of micelles formed by ionogenic surfactants are proposed. The apparent dissoc... see more

Surfactants are amphiphilic molecules having a hydrophilic or water soluble moiety (head group) and a hydrophobic, or water insoluble moiety (tail group). Surfactants are not only related to soaps and detergents, they are also in heavy demand for industri... see more

For intensification of the imbibition process of porous systems and for displacing liquids by other liquids, particularly in secondary oil production, the polycomplexes based on synthetic polyelectrolytes and non-ionic surfactants are of interest. The sur... see more
