Description
An extractive spectrophotometric method has been standardized for the analysis of zirconium in the range of 12 to 60 micrograms. The method involves the extraction of zirconium from 1.0 M nitric acid solution into 0.1 M HTTA in benzene and its determination in the organic extract by spectrophotometry as Arsenazo III complex. Interference due to iron and plutonium can be suppressed by the addition of ascorbic acid and hydroxyl amine hydrochloride prior to NTTA extraction. Cerium upto 1.6 mg and U(VI) upto 50 mg do not interfere. Th upto 1 mg also does not interfere significantly. The overall precision of this method has been found to be +- 2.5%. It is adaptable for the analysis of zirconium arising from the possible dissolution of zircaloy cladding during dissolution of irradiated uranium fuels in Purex process. (author)
