Description

A complex method for analysis of superconductor and similar materials on Y-Ba-Cu basis has been developed, which comprises yttrium and copper determination by their indicator spectrophotometric titration by EDTA and/or complexone 4 in the presence of arsenazo 3. The use of complexone 4 is more favourable. Titration is carried out at λ=650 nm. The method has a sufficient accuracy, provides for rapid determination and does not reguire preliminary separation of components
