Spectrophotometric determination of di-butyl phosphate in PUREX solvent using peroxo disulfate as oxidizing agent
A spectrophotometric method has been developed for the estimation of di-butyl phosphate present in a solution of TBP in n-DD. The quantitative conversion of NaDBP brought from TBP phase in to phosphate ion was achieved in a single-step digestion with potassium peroxo di-sulfate in dilute sulfuric ac...

Summary: | A spectrophotometric method has been developed for the estimation of di-butyl phosphate present in a solution of TBP in n-DD. The quantitative conversion of NaDBP brought from TBP phase in to phosphate ion was achieved in a single-step digestion with potassium peroxo di-sulfate in dilute sulfuric acid solution at 400–410 K. The concentration of the resultant phosphate ion and equivalent HDBP was determined in the form of ammonium molybdo phosphate by spectrophotometry. The accuracy and precision of this method was found to be less than ± 6.4% for the HDBP concentration ranging from 30 to 200 mg/L in the organic sample. |
