Description

Crystalline silico-titanate (UOP) and ammonium molybdophosphate - polyacrylonitrile (AMP-PAN) are tested as sorbents for purification from cesium of concentrated acid wastes of Idaho National Engineering and Ecological Laboratory (INEEL). Using solutions simulating concentrated wastes isotherms of sorption equilibrium are built. Experiments on nonequilibrium sorption are done in columns with 1.5 cm3 volume with flow rate 5, 10, and 20 1/h. Results obtained are compared for two sorbents

Abstract (Russian)

Кристаллический силикотитанат (UOP) и композиция молибдофосфат аммония - полиакрилонитрил (AMP-PAN) испытаны в качестве сорбентов для очистки от цезия концентрированных кислых отходов Национальной технологической и экологической лаборатории Айдахо (INEEL). С использованием растворов, моделирующих концентрированные отходы, построены изотермы сорбционного равновесия. Эксперименты по неравновесной сорбции проведены в колонках объемом 1.5 см3 при объемной скорости потока 5, 10 и 20 1/ч. Полученные результаты сопоставлены для двух сорбентов
