Method for purification of water with removal of uranium with use of dynamical membranes that are formed on basis of hydroxocompounds on aluminum and polyvinyl alcohol with following ultra-filtration on solid polymer or inorganic membranes with average diameter of pores from 0.01 mkm to 0.25 mkm. To form dynamical membrane one additionally uses sodium metasilicon at following salt concentrations: aluminum chloride - 2,8·10 mol/dm, sodium metasilicon - (2,0-2,82)10 mol/dm, with use of polyvinyl alcohol - 3,3·10 g/dmat uranium concentration 5-100 mg/dm, at that that pH of solution ist 5,3-7,0 pH units that is obtained by introduction of sodium hydroxide. |
