This paper describes an analytical method for the quantitation of iron, cobalt, nickel, and copper in lanthanum fluoride at trace levels with graphite furnace atomic absorption spectrometry (GFAAS) without using any matrix modifier. These metals were preconcentrated in HNO3 and analyzed directly. The detection limits for iron, cobalt, nickel, and copper were found to be 3, 1, 2, and 2 ppb, respectively. The average precision of measurements (°/o RSD) for all the elements was <10%.
