For estimating the values corresponding to the oxygen defects in high Tc superconducting oxides, iodometry has been applied for the determination of Cu3+ and Cu2+. The presence of Bi or Pb causes some difficulty in the identification of the end point

Coherent forward scattering spectroscopy having the Voigt configuration was applied in the determination of copper in steels, zinc and tin. Copper (0.0005–0.2%) in these metals could be determined without preconcentration procedure. The relative st

Spectrophotometric determination of nitrogen, as ammonia, with organic solvent extraction has been studied. The blue coloured compound formed from ammonia, phenol and hypochlorite (chloramine-T) is completely extracted with isobutyl alcohol or isoamy
