Application

Triisooctylamine has been used in:
  • determination of uranium isotopes in various environmental samples by liquid-liquid extraction and α spectrometry
  • extraction of uranium from sulphuric acid leaches of uranium-bearing ores
  • extraction of Pd(II), Rh(III), Ir(III), Au(III) and Pt(IV) from hydrochloric and hydrobromic acid

Method for determination of plutonium isotopes in various environmental samples is presented. The separation and purification of plutonium is attained by extraction chromatography with triisooctylamine - polyethylene resin in nitric and hydrochloric acid media. Plutonium is measured by alpha-particle spectrometry
