AG MP-1 anion exchange resin has been reported to be an effective chromatographic technique choice for the complete separation of Cu, Fe and Zn in geological samples. In the cases of Fe being the only interested element, AG1-X4 showed better separation efficiencies. In this work, an effective Fe separation procedure has been successfully established using small amount of AG1-X4 anion exchange resin, aiming to speed up separation, to reduce consumption of regents and to lower down the regent background. Comparison with AG MP-1 has been also made. Fe isotope compositions have been measured on geological reference materials, namely BCR-2, BHVO-2, BIR-1a, AGV-2, W-2, GSP-2, COQ-1, DTS-2b from USGS (United States Geological Survey), JB-2, Jsd-1 from GSJ (Geological Survey of Japan) as well as GBW07105 and GBW07267 from RMRC (National standard reference materials research center). With the analytical results being identical with those reported values within analytical errors, the described separation method and reported data set may serve as valuable references for iron isotopic studies.
