The usage of zeolites for dynamic sorption of cesium from waste waters of nuclear power plants

Use of mathematical modeling for comparative evaluation of sorption capacity of natural and synthetic zeolites in relation to cesium

“…The Si-pin detector was equipped with a collimator Ø2.5 mm and a polyvinylchloride absorber 150 μm thick. The relative error of the measurements was 5 % [5,6].…”

“…For modeling of dynamic conditions of sorption was used installation (Fig. 1) [5]. The installation consists of: pump, sorption column with cartridge, reservoir, measuring tank.…”

“…The sorption of cesium by zeolites (naturalclinoptilolite and synthetic -zeolite NaX and zeolite NaA) under dynamic conditions has been described in the works published earlier by us [5,6]. Dynamic conditions include multiple circulation of cesium containing solution through the sorbent layer.…”

PIXE in the studies of stable cesium sorption from water solutions

“…Schematic of the sorption facility: 1 – sorption column; 2 – water pump; 3 – measuring tank, 4 – reservoir‐collector; 5, 6 – supply and drain valves, respectively; and 7 – air supply for normalizing the pressure inside the sorption system and for normal water pump operation …”

“…There are publications, where PIXE was used to determine the content of cesium and other elements in the soil, biosubstrates, plants, water, and so on. Comparison between the possibilities of PIXE and other analytical technologies in evaluation of Cs content in the environmental objects has demonstrated good metrological characteristics of the method.…”
