ABSTRACT:
An improved internal standard for use in determining the concentration of decomposition products of tributyl phosphate in solvent used for solvent extraction. The improved internal standard includes deuterated variants of the decomposition products to be measured, e.g., deuterated dibutyl and monobutyl phosphoric acids. The use of deuterated dibutyl and monobutyl phosphoric acids eliminates the use of diazomethane, which is toxic and explosive, thereby providing a safer laboratory technique for routine analyses required to monitor production solvent extraction processes.
