Изобретение относитс к способам извлечени плутони из азотнокислых растворов и может быть использовано дл определени содержани плутони в объектах внешней среды.The invention relates to methods for extracting plutonium from nitric acid solutions and can be used to determine the content of plutonium in environmental objects.
РЬвестен способ извлечени плутони из азотнокислых растворов, заключающийс в том, что в азотнокислый раствор, содержащий плутоний, ввод т моноизооктиловый эфир метилфосфоновой кислоты, толуол и раствор хлорного железа с последующим отделением образовавшегос осадка железной соли моноизооктилметилфосфоновой кислоты, содержащего плутоний, от раствора.The brewer is a method of extracting plutonium from nitric acid solutions, which consists in introducing methylphosphonic acid monoisoctyl ester, toluene and ferric chloride solution into a nitrate solution containing plutonium, followed by separating the precipitated iron salt, monoisoctylmethyl pattern and
Цель изобретени - очистка плутони от урана и америци .The purpose of the invention is the purification of plutonium from uranium and americium.
Дл этого используют предварительно синтезированную порошкообразную железную соль моноизооктнлметилфосфоновой кислоты.For this, pre-synthesized powdered iron salt of monoisooctyl methylphosphonic acid is used.
Пример. В азотнокислый раствор объемом 2 л, содержащий смесь плутони (1,05-10-1 Ки/л), америци (1,2-10-8 Ки/л) и урана (2 мг/л), ввод т 0,3 г миомфатаExample. In a 2 l nitrate solution containing a mixture of plutonium (1.05-10-1 CI / l), americium (1.2-10-8 CI / l) and uranium (2 mg / l), enter 0.3 g miomfata
железа. Раствор перемешивают в течение 30 мин и затем добавл ют 1,4 мл толуола, после чего смесь перемешивают еще в течение 10 мин. Образовавшийс осадок отдел ют от раствора путем его фильтрации через два сло марли и определ ют его а-активность измерени на сцинтилл ционном а-счетчике с использованием эталонов с соответствующим слоем осадка.gland. The solution was stirred for 30 minutes and then 1.4 ml of toluene was added, after which the mixture was stirred for another 10 minutes. The precipitate formed is separated from the solution by filtering it through two layers of gauze, and its a-activity is measured on a scintillation a-counter using standards with an appropriate layer of sediment.
Полученна а-активность (5,85-10 Ки) обусловлена только нлутонием-239. Выход плутони 87%.The resulting a-activity (5.85-10 Ci) is due only to nlutonium-239. The yield of plutonium is 87%.
