A method was developed fhr the photometric determination or copper in iron and steel with the use of diphenylcarbazone. The copper derivstive of diphenylcarbazone is insoluble in water but is well extracted with benzene and its homologues; the intensity of the red extract obeys Lambert-Beer's law. The reaction described is specific and highly sensitive. It permits the detection of the tenths parts of a microgram of copper. Iron is combined as soluble phosphate complex. The experi mental error of the determination of copper in iron and steel does not exceed 4%. (tr-auth)
