【Abstract】 Samples of Zircaloy were dissolved in HC1 with dropwise addition of HF. The cooled solution was diluted with H2O, and Mn, Mo, Ba, Mg,Cu, Co, Ca, V, Al, Ti, Pb, Ni and Hf were determined directly by inductively coupled plasma atomic emission spectrometer (ICP-AES) with matrix-minor components matching. Interference of coexisted elements and effect of matrix and acidity in the sample solution were discussed. For the sample solution containing 10 mg.ml-1 of Zircaloy, the detection limits ranged from 1.3 to 33 ug. g-1 of Co and Pb respectively. The rate of recovery is ranging from 92% to 124%, the relative standard deviation is within 7%.更多还原
