Scintillating extraction chromatographic resin for quantification of aqueous radioactivity

Radionuclide Sensors Based on Chemically Selective Scintillating Microspheres: Renewable Column Sensor for Analysis of99Tc in Water

“…We believe that with further development of radionuclide-selective scintillating materials and advances in scintillation light detection and signal-processing techniques, ,− this radionuclide-sensing approach will represent a useful platform for the development of effective radiochemical probes for field analytical instruments and process control applications.…”

“…This work resulted in practically no follow-up work relevant to radiochemical analysis . Recently, a flow cell containing scintillating glass beads derivatized with chelating ligand for the extraction and detection of radionuclides was described in a proceedings paper by DeVol and co-workers . These investigators subsequently reported impregnation of scintillating polymer beads with extractants for radionuclide sensing .…”

Radionuclide Sensors for Environmental Monitoring: From Flow Injection Solid-Phase Absorptiometry to Equilibration-Based Preconcentrating Minicolumn Sensors with Radiometric Detection

“…Subsequently, these authors described scintillating glass beads coated with organic extractants for the detection of radionuclides. 2 These investigators also reported impregnation of polymer beads with extractants and scintillators for radionuclide sensing. 75 Similarly, Egorov and co-workers described impregnation of both extractant and scintillating fluors in polymer beads, and characterized the analytical performance of the material in minicolumn sensors for 99 Tc.…”

“…This work that has largely occurred from 1995 to the present. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] As a secondary aim, we will cover radionuclide sensors that combine sorption and scintillation in formats other than minicolumn sensors. We are particularly concerned with the detection of Rand β-emitting radionuclides in liquids, which presents particular challenges as we shall describe below.…”

Separation and subsequent determination of low radioactivity levels of radium by extraction scintillation

“…TOPO is a good extractant for uranium in 2MHNO 3 , while alkali metals, alkaline earth metals, iron, aluminium, are not extracted [16,17].…”
