Isolation of iron and strontium from liquid samples and determination of 55Fe and 89,90Sr in liquid radioactive waste

Development of a protocol to measure iron-55 in solid matrices in the environment

“…Environmental samples usually exhibit significant levels of elemental iron. Measuring elemental iron before and after the chemical treatment can help quantify the extraction efficiency of iron-55 (Skwarzec et al, 2001;Grahek and Ro zmari c Maĉefat, 2006;Grahek and Ro zmari c Maĉefat, 2004). Elemental iron is used both as a tracer and a carrier.…”

“…The quantification of elemental iron (amotteag ege and M.) may be done using gravimetry (iron hydroxyde precipitate), Atomic Absorption Spectrometry (SAA) (Skwarzec et al, 2001;Grahek and Ro zmari c Maĉefat, 2006), Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) (CETAMA, 2001) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS).…”

“…The colour of solutions from the chemical treatment is based on the quantity of ferrous ion Fe 3þ present (orange cation) (Grahek and Ro zmari c Maĉefat, 2006). The intensity of this colouration lessens the detection yield.…”

“…In the literature, six types of chemical treatments (Grahek and Ro zmari c Maĉefat, 2006;Grahek and Ro zmari c Maĉefat, 2004) were selected for liquid scintillation measurement. These protocols must be adapted to the needs of the analyst.…”

A Simple and Fast Separation Method of Fe Employing Extraction Resin for Isotope Ratio Determination by Multicollector ICP-MS

“…Trioctylmethylammonium chloride (Aliquat 336) works as an anion exchanger, and is used in extraction chromatography (commercially sold as TEVA resin) [1]. Yang and Pin [2] and Grahek and Macefat [3] have tried to use the TEVA resin for Fe separation. The eluent volumes of 60 mL for 1 mL of the TEVA resin and 120 mL for 3 g (equates ~2.7 mL) TEVA resin were used, respectively.…”
