“…Direct photometric determinations of extracted metals in organic solvents have been developed based on the addition of a chromophoric agent to the organic phase. Thus, Sm and Eu extracted into TBP can be spectrophotometrically determined following the addition of phen or TTA (645), U extracted into TOA by carminic acid addition (1027), V extracted with benzoinoxime (604), or Mn extracted with DEDTC (687) by 8-quinolinol addition, Fe extracted with DOPA by thiocyanate addition (172), and Th extracted by DOPA can be determined using arsenazo III reagent (171). In the photometric determination of Hg in dithizone, interference from Cu was eliminated by measuring absorbances at isobestic points for the copper dithizonatedithizone system (9).…”
