Description
содержащего - 107 Ки/л цели -137. После достижени проскока по цезию смолу промывают 100 см3 дистиллированной воды, 60 см3 1 % гидроксида натри и элюируют ра- циоцезий солевым раствором состава, г/л: CaClz 6Н2О - 44,5; MgClz 6H20 - 10,2; KCI - 29,8; рН 6-8 в количестве 150 см3 , скорость элюировани 30 см /ч. Отработанный солевой раствор пропускают через колонку , заполненную 3 см3 гранулированного сорбента на основе ферроцианида меди (сорбент МЖА; ТУ 002-91), с содержанием основного вещества 50 мг/г.containing - 107 Ci / l target -137. After the cesium slip has been achieved, the resin is washed with 100 cm3 of distilled water, 60 cm3 with 1% sodium hydroxide and the raciocesium is eluted with saline solution, g / l: CaClz 6Н2О - 44.5; MgClz 6H20 - 10.2; KCI - 29.8; pH 6-8 in an amount of 150 cm3; elution rate 30 cm / h. The spent saline solution is passed through a column filled with 3 cm3 of a granular sorbent based on copper ferrocyanide (MFA sorbent; TU 002-91), with a basic substance content of 50 mg / g.
Солевой раствор после пропускани через ферроцианидный сорбент анализируют на содержание цези -137 и при коэффициенте очистки более 102 направл ют на повторное использование в следующем цикле очистки молока.After passing through a ferrocyanide sorbent, the saline solution is analyzed for cesium -137 and, with a purification coefficient of more than 102, is sent for reuse in the next milk purification cycle.
Всего через 3 см3 ферроциэнидного сорбента до достижени заданного коэффициента очистки от 137Cs было пропущено 12 л солевого раствора, что позволило провести 80 циклов элюировани радиоцези со смолы без замены элюирующего раствора. Содержание ионов меди в циркулирующем солевом растворе не превышает 0,2 мг/л, Fe(CN)e ионов 0.05 мг/ , ионов С и Fe(CN)e в очищаемом молоке не обнаружено .Just 3 cm3 of the ferrocyenide sorbent, until reaching the desired purification coefficient of 137Cs, 12 L of saline solution was passed, which allowed 80 cycles of elution of the radiocaesium from the resin to be carried out without changing the elution solution. The content of copper ions in the circulating saline solution does not exceed 0.2 mg / l, Fe (CN) e ions 0.05 mg /, C and Fe (CN) e ions in the purified milk were not found.
Примеры 2-4. Процесс ведут аналогично примеру 1 с использованием сорбента МЖА с различным содержанием Examples 2-4. The process is carried out analogously to example 1 using an MBA sorbent with different contents
ферроцианида меди. Данные приведены в таблице.copper ferrocyanide. The data are given in the table.
Представленные данные показывают, что проведение процесса в за вленном режиме позвол ет обеспечит многократное (до 90 циклов) использование солевого раствора в процессе очистки молока за счет достижени высоких коэффициентов очистки от 137Cs и практически полного отсутстви загр знени солевого раствора продуктами деструкции ферроцианидного сорбента.The presented data show that carrying out the process in the specified mode allows for multiple (up to 90 cycles) use of the saline solution in the milk purification process due to the achievement of high purification coefficients from 137Cs and the almost complete absence of contamination of the saline solution with ferrocyanide sorbent degradation products.
При проведении процесса по способу- прототипу загр зненный радиоцезием регенерирующий солевой раствор направл ют на захоронение, при этом объем радиоактивных отходов составл ет 16,7% от обьема очищенного молока. При осуществлении за вленного способа объем радиоактивных отходов уменьшаетс по сравнению с прототипом в 550 раз, а расход реагентов на приготовление солевого регенерирующего раствора в 30-50 раз (за счет потерь солевого раствора при его циркул ции в количест- ве 2-3% за цикл).When carrying out the process according to the prototype method, the regenerating saline solution contaminated with radiocaesium is sent for disposal, while the volume of radioactive waste is 16.7% of the volume of purified milk. When implementing the inventive method, the volume of radioactive waste is reduced in comparison with the prototype by 550 times, and the consumption of reagents for the preparation of a salt regenerating solution by 30-50 times (due to the loss of salt solution during its circulation in the amount of 2-3% per cycle )
