Abstract:There was no test method for asbestos in oxide scale in China so far. In this paper, after the sample was dispersed with isopropanol and followed by suction filtration onto the glass fiber filter, a method was proposed for determination of chrysotile, crocidolite and amosite in oxide scale by X-ray diffraction absorption base standard correction method. The linearity of calibration curves for determination of chrysotile, crocidolite and amosite was good. The detection limit was 0.004 5%, 0.002 3% and 0.000 65%, and the lower limit of quantitation was 0.014%, 0.006 9% and 0.002 0%, respectively. The prepared oxide scale with 0.20% of asbestos was analyzed. The relative standard deviations (RSD, n=10) of determination results were all less than 8%. The proposed method was verified with the oxide scale sample. The determination results of asbestos were consistent with the reference values. The method could meet the detection requirements for trace asbestos in oxide scale with mass fraction of 0.10%-0.50%.
