A new, simple and fast separation method for Fe using an extraction chromatographic resin, Aliquat 336 (commercially available as TEVA resin) has been developed. A one milliliter column containing 0.33 mL TEVA resin on 0.67 mL CG-71C was used. Iron was adsorbed with 6 mol·L−1 HCl + H2O2 on TEVA resin, and recovered with 2 mol·L−1 HNO3. The recovery yield and total blank were 93.5 ± 6.5% and 6 ng, respectively. The separation method is simple, and takes

A new, simple and fast separation method for Fe using an extraction chromatographic resin, Aliquat 336 (commercially available as TEVA resin) has been developed. A one milliliter column containing 0.33 mL TEVA resin on 0.67 mL CG-71C was used. Iron was adsorbed with 6 mol·L−1 HCl + H2O2 on TEVA resin, and recovered with 2 mol·L−1 HNO3. The recovery yield and total blank were 93.5 ± 6.5% and 6 ng, respectively. The separation method is simple, and takes <2 hours. For evaluation of the Fe separation, Fe isotope ratios were measured by a double-spike method employing multicollector inductively coupled plasma source mass spectrometry (MC-ICP-MS) with repeatability of 0.06‰ (SD) for the standard solution and ~0.05‰ for the silicate samples. Therefore, the column chemistry developed in this study is a viable option for Fe isotope ratio measurement by MC-ICP-MS.
