Abstract
A Method for the atomic absorption spectrometric determination of 0.0010.03% of iron in titanium, copper and magnesium was investigated. The recommended conditions were: wavelength 248.3 mμ, current of hollow cathode lamp 30 mA, slit width 0.25 mm, air pressure 1.8 kg/cm2 and acetylene pressure 0.17 kg/cm2. Iron in titanium, copper and magnesium could be determind by atomic absorption measurement after extraction with MIBK. Much higher sensivity was obtained for iron in titanium by using oxine-MIBK extraction. The matrix elements and other constituents usually contained in titanium, copper and magnesium did not interfere. The method was very rapid and the results of recovery test on practical samples were satisfactory.
