Description
Известны способы извлечени катионов нереходных металлов из растворов нутем сорбции их на слабо- и среднеосновиых анионах в гидроксильной форме.Methods are known for the extraction of non-transition metal cations from solutions of their sorption on low- and medium-base anions in hydroxyl form.
С целью интенсификации ироцесса предлагаемс исиол153овать анионит н карбонатной форме и между процессами сорбции (после проскока извлекаемого катнона) иоинт обрабатывать раствором карбоната или гидроокиси натри .In order to intensify the process, it is proposed to prepare the anion exchanger in the carbonate form and between the sorption processes (after the overrun of the recovered quatone) and the joint should be treated with a solution of sodium carbonate or sodium hydroxide.
При обработке аниоиита указанными растворами происходит восстановление сорбцнонной емкости анионита в OTHOIHCIHHI катионов переходных металлов без десорбции этнх катионов , что ноз ол ет проводить процесс сорбцни несколько раз и повысить сорбционную снособност) анионнта.When anioiite is treated with these solutions, the sorption of the anion exchanger in OTHOIHCIHHI of transition metal cations is restored without desorption of ethn cations, which most often carry out the sorption process several times and increase the sorption capacity of the anion.
После заверн. цикла сорбции 1 ымывапне поглощенных катионов ир01юд т растворами кислот или аммиачной водой.After wrapped. the sorption cycle 1 of the absorbed cations is irradiated with acid solutions or ammonia water.
Пример. В иопитовую колонку загружают анпоннт, например .ЭДЭ10П в карбонатной форме. Через колонку пропускают раствор сульфата никел со скоростью 0.12-Q,QQ л/час. Процесс сорбции осуществл ют до проскока извлекаемого катиона. Затем колонку промывают дистиллированной водой, обрабатываюг 1-50/о-ным раствором карбоната натри пли едкого патра, промывают водой и вновь осу1цест15л ют процесс сорбции. Полный цикл сорбции, включающий сорбцию, промывку, обработку щелочным или карбонатным раствором и промывку водой, повтор ют до истощени поглотительной способности иопита.Example. An upon is loaded into the iopitic column, for example .EDE10P in carbonate form. Nickel sulfate solution is passed through the column at a rate of 0.12-Q, QQ l / hr. The sorption process is carried out before the breakthrough of the recovered cation. The column is then washed with distilled water, treated with 1–50 /-solution of sodium carbonate or caustic Patra, washed with water and the sorption process is again carried out. The complete sorption cycle, including sorption, washing, treatment with an alkaline or carbonate solution and washing with water, is repeated until the iopite's absorption capacity is depleted.
При проведении щести циклов сорбции на колонке, содержащей 3 г сухого анионита в карбонатной форме, было иоглощено 926,04 .wj никел , что соответствует 10,45 мг же на 1 г сухого ионита. При регенеранни анионнта кислотой после шести циклов сорбц 1и ()ыло извлечено 916,5 мг никел , что соответCTiiycT 10,4 мг When conducting sorption cycles on a column containing 3 g of dry anion exchanger in carbonate form, 926.04 .wj nickel was absorbed, which corresponds to 10.45 mg per 1 g of dry ion exchanger. When the anion was regenerated with acid after six cycles, sorbts 1i () recovered 916.5 mg of nickel, which corresponds to a CTiiycT of 10.4 mg
После первого цикла сорбцип было поглощено 206,0 мг никел .After the first cycle, the sorbcy absorbed 206.0 mg of nickel.
Следовательно, при проведении И1ести последовательных циклов сорбции с промежуточиой обработкой поглотительна способность колонки но никелю повьпиаетс примерно 15 4,5 раза.Consequently, when conducting successive sorption cycles with intermittent treatment, the absorptive capacity of the column but nickel is approximately 15–4 times repeated.
