Rapid Spectrophotometric Determination of Technetium in Uranium Materials.

Spectrophotometric Determination of Technetium with 1,5-Diphenylcarbohydrazide.

“…The Tc(V) -thiocyanate complex in acetone-water medium is also the basis of a spectrophotometric determination (2).…”

Determination of technetium by atomic absorption spectrophotometry

“…Boyd (3) described a polarographic method capable of determining 5 X 10-* gram. Technetium is determined spectrophotometrically as a thiocyanate (4, 5), or 1,5-diphenylcarbohydrazide (6,7) complex with a sensitivity of 1 X 10-7 gram. Using the 4031 A spectral line, as little as 1 X 10~2 34567 8gram can be determined by emission spectrometry (8).…”
