The article presents the basic theoretical principles, the formulation of mathematical models and detailed presentation of the areas of application of the method of solvent sublation together with a description of the relevant works of researchers from different countries. To date, there is not enough effective method for pre-concentration, separation or purification of aqueous solutions of target components or contaminants that would allow reducing the consumption of reagents and allowed to work with large volumes of dilute aqueous solutions. This method combines the advantages of flotation and extraction. So solvent sublation allows to use small amounts of organic solvents and can effectively concentrate the matter for further purposes. The main factors that affect the process are pH, type of organic solvent, ionic strength, surfactant, temperature, rate of gas bubbling. Above these and other conditions of the process many scientists are working and at this stage of is study it is already known and proven main key parameters that can predict the effectiveness solvent sublation on its use for different purposes. Among the numerous applications is solvent sublation previous sample preparation to analysis, the concentration of noble metals, extraction of herbal components, separation of important enzymes of solutions, wastewater treatment from organic substances, toxic elements, dyes and detergents. Promising areas of application is the use of this method for the synthesis of nanoparticles of various materials.Downloads
