Statistical suitability testing of 3M Empore™ Sr disc and AnaLig® Sr-01 use for 90Sr determination

Abstract

In this paper rapid separation methods for strontium determination using molecular recognition technology products 3M Empore TM Sr disc, AnaLig Ò Sr-01 and extraction chromatography Sr Ò Resin were presented and statistical tested. The methods performance was investigated by analysis of NPL (High Alpha-Beta 2003) and (High Alpha-Beta 2005) intercomparison samples. The presented results were evaluated as correct for all experimental data. We used linear regression (with regression diagnostics), t test and the mean of variable using 90 Sr with 3M Empore TM Sr disc, AnaLig Ò Sr-01 and Sr Ò Resin.

Statistical suitability testing of the Aliquat-336, AnaLig® Pu-02 and TRU® Resin use for the 239,240Pu, 238Pu determination

“…Analyzing of samples by solid phase extraction (SPE) methods can clearly be faster than traditional liquid-liquid extraction methods. A variety of SPE materials called AnaLig have been developed using ''molecular recognition'' ligands on solid supports and commercialized by IBC Advanced Technologies [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Plutonium can be found in environmental samples as a fallout from nuclear weapons tests, nuclear reactor accidents, discharges from reprocessing plants and radioactive waste.…”

“…AnaLig Ò Pu-02 column packing may be used for the removal of Pu(IV) ions from several molar acid solutions and solutions of higher pH. In the absence of Pu(IV) it also has some affinity for Fe(III) [5,7,9,11,[14][15][16][17][18][19][20]. Plutonium can be separated by liquid-liquid extraction with 30 % Aliquat-336 in toluene.…”
