Аннотация: The entrance of even a small amount of phosphorus compounds into natural waters leads to global problems that require the use of modern purification technologies. The main methods for extracting phosphorus from aqueous solutions discussed in the literature and used in industry are anaerobic biochemical digestion, liquid extraction,Показать полностьюcrystallization, etc. Membrane methods for removing phosphorus compounds are under development. We use here a hybrid electrobaromembrane process used to separate different ions of the same sign of charge. Separated ions move in an electric field through the pores of a nanoporous membrane to the corresponding electrode, while a commensurate counter convective flow in the pores is created by a pressure drop across the membrane. In recent works, the EBM method has been successfully used to separate ions of strong electrolytes (for example, Li+/K+ or Li+/Na+). It was shown that the method makes it possible to achieve high selectivity in the extraction of lithium ions at fluxes of separated ions comparable with other membrane methods.
