1. Introduction
Trioctylmethylammonium chloride (Aliquat 336) works as an anion exchanger, and is used in extraction chroma-tography (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. However, these volumes are too mamy to handle; large space is required and evaporation takes a long time. Re-cently, Makishima and Nakamura [4] successfully puri-fied Zn using a one milliliter column composed of 0.33 mL TEVA resin on 0.67 mL CG-71C resin. They used the advantage of acid resistance of the TEVA resin [5], namely, HNO3 was used in the final step to recover Zn that was strongly adsorbed on the resin. Based on this novel finding, it was noticed that the anionic character of the TEVA resin could be applied to separation of Fe. This study applies the TEVA resin for purification of Fe for isotope ratio measurements using multicollector (MC)-ICP-MS for the first time.
