NEW AND IMPROVED ANALYSES FOR TRI-N-BUTYL PHOSPHATE
The acid-saturation, decomposition, and uranium-saturation methods for the indirect determination of TBP were evaluated. The decomposition method is based on a conversion of the TBP to phosphoric acid followed by spectrophotometric or volumetric determination of the phosphate. The acid- saturation method consists of contacting the organic solvent containing TBP with a nitric acid solution and determining the amount of acid extracted into the organic phase. The uranium-saturation method consists of contacting the organic phase with a uranyl nitrate solution, and the amount of uranium extracted is determined fluorometrically or spectrophotometrically. New and improved versions of the saturation method are reported. The various reported versions of the decomposition method were not satisfactory either because of the excessive time and care required to obtain a complete conversion of TBP to phosphate or because of incomplete and variable decomposition of TBP.
