Validation of an extraction chromatographic method with SrResin® for determination of 210Pb in various matrices

Abstract

A radiochemical method for the determination of 210 Pb in various types of samples was validated. An extraction chromatographic material Eichrom SrResin ® was used for Pb separation. From the resin, Pb was eluted with 6 M HCl. The method was tested for water, inorganic and organic matrices. As a main result of the study, activity concentrations of 210 Pb in 19 food samples of the main Czech food-basket items were determined. Results ranged from 0.03 ± 0.01 Bq kg -1 to 1.54 ± 0.40 Bq kg -1 , fresh mass.

Radiochemistry

“…The radioactive waste from accelerators can include many quite long-lived radioisotopes and a detailed account of their analysis 332 by accelerator mass spectroscopy has recently been published. Other recent publications have given special procedures for the determination of radiostrontium 333 and of lead-210 334 as well as the speciation of technetium, rhenium 335 and of airborne lead-210 and polonium-210. 336 A comparison has been made between a-spectroscopy and quadrupole ICP-MS in the determination of the 234 U/ 238 U ratio in natural water samples, 337 good agreement was found.…”

Activity of natural radionuclide 210Pb in different foodstuffs in the Czech Republic and its annual intake

“…Determination of 210 Pb activity concentrations. 210 Pb activities were determined by radiochemical analysis, described in (Bartusková et al 2006). Food samples were bought in 3 shops in 2 big cities in the northern Moravia, north-eastern part of the CR.…”

Radionuclide Monitoring

“…DDTC, EDTA, TIOA, TOPO, TLA and Aliquot 336 have also been proven to obtain separation efficiency for Po. Although anion exchange (AG 1 ×4), cation exchange (AG 50W-×8) resin and solid phase extraction resin e.g., Sr-resin (Bartusková et al, 2006) have been applied for Po purification, solvent extraction is still the most commonly used method.…”
