Abstract

Способ очистки водных солевых растворов от железа, включающий обработку раствора воздухом при температуре выше +25°C и pH раствора в области нейтральных значений, отличающийся тем, что после аэрации в раствор последовательно вводят водный раствор перекиси водорода, затем гидроокись щелочного и/или щелочноземельного металла, при pH раствора 6,5-8,5 ед., а затем нагревают до температуры от +25 до +50°C. A method of purifying aqueous salt solutions from iron, comprising treating the solution with air at a temperature above + 25 ° C and a pH of the solution in the region of neutral values, characterized in that after aeration, an aqueous solution of hydrogen peroxide is subsequently introduced into the solution, then an alkali and / or alkaline earth metal hydroxide , at a pH of the solution of 6.5-8.5 units, and then heated to a temperature of +25 to + 50 ° C.
