• Atomic absorption spectrometric determination of copper in aluminium alloys and steels was established, whereby a quite linear calibration curve was obtained for 0〜40μg Cu/ml in 0.3〜0.7N hydrochloric acid solution in the presence of aluminium (0.05〜0.3 g/25 ml) and iron (0.1〜0.5 g/25 ml). When the diethyldithiocarbamate-MIBK extraction was applied to the analysis of micro-amount of copper, the sensitivity of the method was ten-fold multiplied, and the 0.003% Cu in aluminium metal could be determined. The conditions recommended were as follows : wavelength 3247A, hollow cathode lamp current 30 mA, slit width 0.025mm, air pressure 1.5 kg/cm^2, and acetylene pressure 0.5 kg/cm^2 for aqueous solution and 0.3 kg/cm^2 for MIBK solution with the water cooling of the burner.
