抄録

The differential spectrophotometric method was applied to the determination of chromium in ferrochromium and high chromium alloys. Chromium was determined by reading the absorbance of chromium (VI) in 1 N-HClO4 at 350 mμ against the reference solution which contained 16.0 mg chromium per 100 mL. The common alloying elements iron, nickel and manganese did not interfere up to about 50 per cent concentration. However, when samples contained over 50 per cent of iron, it was removed by solvent extraction from hydrochloric acid solution. Similarly titanium and cobalt in concentration up to 20 per cent did not interfere.
