Spectrophotometric determination of trace uranium with Eriochrome Azurol B and Chrome Azurol S in the presence of the cationic surfactant Septonex.
Procedures for the spectrophotometric determination of UO(2+)(2) with Eriochrome Azurol B and Chrome Azurol S in the presence of the cationic surfactant Septonex have been developed from studies of the complex equilibria in solution, and simplex and single-factor optimization. They are suitable for the determination of UO(2+)(2) in drinking, surface and waste waters after prior separation with tri-n-octylamine in benzene or Freon 113 from 4M hydrochloric acid and stripping with 0.3M hydrochloric acid.
