Изобретение относитс к области получени двойных соединений фосфата уранила с одновалентным катионом и может быть использовано , в частности, в аналитической химии урана.The invention relates to the field of producing double uranyl phosphate compounds with a monovalent cation and can be used, in particular, in the analytical chemistry of uranium.
Известен способ получени двойного соединени фосфата уранила с одновалентным катионом , например натрием, путем взаимодействи ацетата уранила с двухзамещенным фосфатом натри в кислой среде при комнатной температуре.A known method for producing a double uranyl phosphate compound with a monovalent cation, for example sodium, by reacting uranyl acetate with disubstituted sodium phosphate in an acidic medium at room temperature.
Недостаток известного способа состоит в невозможности получени соединени NH4UO2PO4-3H2O строго определенного состава .The disadvantage of this method is the impossibility of obtaining the compound NH4UO2PO4-3H2O of a strictly defined composition.
По предлагаемому способу процесс ведут при рН среды 4,7-4,8. Это позвол ет получать соединение NH4UO2PO4-3H2O строго определенного состава.The proposed method, the process is carried out at a pH of 4.7 to 4.8. This allows the preparation of the compound NH4UO2PO4-3H2O of a strictly defined composition.
Пример. К 50 мл дистилированной воды, подкисленной фосфорной кислотой до рП 4,7, приливают раствор дигидрата уранилацетатаExample. To 50 ml of distilled water, acidified with phosphoric acid to RP 4.7, a solution of uranyl acetate dihydrate is poured
и 0,1 М раствор двухзамещенного фосфата аммони ; рН среды поддерживают сливанием исходных растворов иО2(СНзСОО)2-2Н2О и (NH4)2HPO4 при соотношении - 1 : 0,8.and 0.1 M solution of dibasic ammonium phosphate; The pH of the medium is maintained by pouring out the initial solutions of IO2 (CH3COOH) 2-2H2O and (NH4) 2HPO4 with a ratio of 1: 0.8.
Образующийс кристаллический осадок фильтруют, промывают водой и сушат на воздухе . Согласно данным химического анализа, полученный продукт имеет следуюш,ий состав (в вес. %):The resulting crystalline precipitate is filtered, washed with water and air dried. According to chemical analysis, the resulting product has the following composition (in wt.%):
иОз 64,8; P2Os 16,0; КНз 3,3, что соответствует формуле NH4UO2PO4-3H2O.64.8; P2Os 16.0; CNR 3.3, which corresponds to the formula NH4UO2PO4-3H2O.
Предмет изобретени Subject invention
Способ получени двойного соединени фосфата уранила с одновалентным катионом путем взаимодействи ацетата ураннла и двухзамещенного фосфата соответствующего одновалентного катиона в водной кислой среде при комнатной температуре, отличающийс тем, что, с целью получени соединени NH4UO2PO4-3n20 строго определенного состава , процесс ведут при рН среды 4,7-4,8.The method of obtaining a double uranyl phosphate compound with a monovalent cation by reacting urannol acetate and dibasic phosphate of the corresponding monovalent cation in an aqueous acidic medium at room temperature, characterized in that, in order to obtain a well-defined compound NH4UO2PO4-3n20, the process is carried out at pH 4, 7-4.8.
