Studies on Analytical Methods for Trace Elements in Metals Using Radioactive Isotope (1st Report). Determination of Zircanium in Steel

Hirosi Amano


Abstract:

The methods of determination of zirconium in steels were studied using the radioactive isotope zirconium-95 as a tracer. Experiments were carried out on the determination of zirconium by the phosphate method, arsenate method, basic selenite method and mandelate method, and on the separation of zirconium from iron by means of mercury cathode electrolysis and ion exchange. From the experimental results, it was recommended to precipitate zirconium as its phosphate after the separation from iron by means of mercury cathode electrolysis.
