Description

Accelerated technique of determination of 1x10-1-1x10-3% REE in the alloyed steels, based on photometry of REE complexes with arsenazo 3, is presented. Preliminary microamounts of REE are separated from the main components of the alloys using extraction chromatography. Di- (2-ethylhexyl)-phosphorus acid was used as extragent. Ssub(r)=0.04-0.10
