Изобретение относитс к способам разделени циркони и гафни экстракцией и может быть использовано в технологии производства соединений циркони и гафни ..The invention relates to methods for the separation of zirconium and hafnium by extraction and can be used in the production technology of zirconium and hafnium compounds.
Известен способ разделени циркони и гафни путем экстракции последнего из сернокислых растворов фосфороорганическими соединени ми, например диалкилфосфатами или пирофосфатами . Коэффициент разделени циркони и гафни ГО-20.A known method for separating zirconium and hafnium by extracting the latter from sulfuric acid solutions is organophosphorus compounds, for example dialkyl phosphates or pyrophosphates. The separation factor of zirconium and hafnium GO-20.
Недостаток способа состоит в низкой эффективности разделени .The disadvantage of the method is low separation efficiency.
Цель изобретени - повышение эффективности разделени циркони и гафни .The purpose of the invention is to increase the efficiency of the separation of zirconium and hafnium.
Поставленна цель достигаетс тем,что экстракцию гафни из сернокислых растворов осуществл ют тетраги дрофу ран ом.This goal is achieved by the fact that the extraction of hafnium from sulfuric acid solutions is carried out with tetragi bustard.
Пример К8,3н сернокислс му раствору, содерлсащему 75,2 г/лExample K8,3n sulfate solution containing 75.2 g / l
циркони и 8,2 г/л гафни (здесь и далее концентрации циркони и гафн.и приведены в пересчете на содержание их двуокисей), добавл ю роданид аммони из расчета 12 г роданида аммони на 1 г циркони (гафни ). Раствор обрабатывают тетрагидрофураном.zirconium and 8.2 g / l of hafnium (hereinafter concentrations of zirconium and hafn. and are based on the content of their dioxides), adding ammonium rhodium at the rate of 12 g of ammonium rhodium per 1 g of zirconium (hafnium). The solution is treated with tetrahydrofuran.
После разделени органической и водной фаз получают экстракт, содержащий 42,5 г/л гафни и 8,3 г/л циркони , и водный рафинат, содержащий 2,3 г/л гафни и 47,6 г/л циркони . Пр мой выход гафни в экстракт составл ет 78,2%. Фактор разделени 32,3.After separation of the organic and aqueous phases, an extract is obtained containing 42.5 g / l of hafnium and 8.3 g / l of zirconium, and an aqueous raffinate containing 2.3 g / l of hafnium and 47.6 g / l of zirconium. The direct yield of hafnium in the extract is 78.2%. The separation factor is 32.3.
Таким образом изобретение позвол ет повысить эффективность разделени циркони и гафни за счет получени более высокого фактора разделени ) по сравнению с известным способом (10-20),Thus, the invention makes it possible to increase the separation efficiency of zirconium and hafnium by obtaining a higher separation factor) as compared with the known method (10-20),
