Abstract

Способ выделения ванадия из водных натрийсодержащих растворов, включающий мембранный вывод катиона натрия из раствора и осаждение поливанадатов аммония, отличающийся тем, что вывод катиона натрия ведут в присутствии аммонийной группы при рН 6,5-7,5 до мольного отношения Na:V<0,1, а осаждение ванадия осуществляют аммиачной водой, протонированной генерируемым ионом водорода.A method for the extraction of vanadium from aqueous sodium-containing solutions, including the membrane removal of the sodium cation from the solution and the precipitation of ammonium polyvanadates, characterized in that the sodium cation is removed in the presence of an ammonium group at pH 6.5-7.5 to the molar ratio Na: V <0, 1, and the deposition of vanadium is carried out with ammonia water protonated by the generated hydrogen ion.
