摘要：

High-performance chelation ion chromatography involving dye-coated resins has been used to determine barium and strontium in samples of mineral water and milk powder containing several orders of magnitude higher levels of calcium and other alkali and alkaline earth metals. Detection limits of 0.03 mg dm(-3) were achieved for both barium and strontium. The technique was used to determine both metals in a river water certified reference material and all results were compared to inductively coupled plasma optical emission spectroscopy producing overall good agreement between the two methods.
