5. Conclusions
Analysis of DBP co
streams of FBTR mixed carbide fuel reprocessing solu-
tions by gas chromatography method was demonstrated.
It is simple, only needs the conversion of DBP into its
methyl ester prior to injection. The major advantage of GC
method is the simultaneous determination of MBP, DBP
and TBP and hydrocarbons in a single aliquot without any
interference using 10% XE-60 column. The reproducibil-
ity and linearity of the method suggest that it is well sui-
table for the determination of DBP over a concentration
in the range from 200 to 1800 ppm and relevant to organic
streams of purex process.
