Chromysheva E. The Isolation of Ionogenic Surfactants from Aqueous Solutions by Precipitating and Sorption Microflotation Methods

The Thesis is devoted to the establishment of colloid-chemical regularities of the ionogenic surfactants and flotation isolation process and to the working out of the effective methods of their isolation from aqueous and technogenical solutions and sewage on the basis of the data obtained. The possibility of the surfactants flotation isolation process intensification by introduction of inorganic arresters, or sorbent to their solutions experimentally confirmed allows to recommend them for the improvement of waste surfactants cut flotation technogenical solutions. The systematic researches have been carried out and the regularities of ionogenic surfactants adsorption on the surfactant solution – solid interphase boundary have been stated to explain and forecast the efficiency of the carrying out of the process of their isolation from aqueous solutions by the method of a sorption microflotation. A new effective method of isolation cationic surfactants Based on the regularities revealed the use of flotation has been offered for waste treatment at machine-building, oil-extraction, and paintwork enterprises.
