“…Due to multi electronic nature, nuclear matrials including U, Th, Zr and different rare earth elements were found to interfere in the determination of analytes especially when they are present at trace level [7][8][9][10][11][12][13][14]. To avoid spectral interference from nuclear materials, mostly the emission rich matrix is selectively extracted by the chemical separation followed by the determination of the raffinate for the analytes [15][16][17][18][19][20].…”

An ICP-AES based method was developed for the direct determination of Phosphorous and Sulphur in U, Th and Zr matrices. Different analytical lines of P and S were identified and the calibration curves were established. Analytical performance of these analytical lines and the spectral interference of U, Th and Zr on these lines were studied systematically. The methodology for direct and trace level determination of P and S was found to be promissing, simple and less time consuming and it was validated using synthetic samples. The method was also found to be compared satisfactorily with the existing methods for their determination.

“…To the best of our knowledge, only two reports are available in the literature for the determination of trace constituents in a thorium matrix. (a) The d.c. arc carrier distillation-based method was reported using a mixed carrier, namely, AgCl+SrF 2 for 22 trace elements with detection limits for the analytes ranging from 0.1-50 ppm, with a precision of 15% (30). The analytical performance of this methodology is not very attractive.…”

“…The atomic emission spectroscopy (AES) technique, being simultaneously multi-elemental and having acceptable analytical performance (detection limits, sensitivity, linear dynamic range, etc. ), is regularly used for the determination of trace metallic analytes in nuclear fuels and associated materials (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17). Zirconium (Zr) is accepted worldwide as a cladding material in the nuclear industry due to its low neutron absorption cross-section.…”

Chemical (ICP-AES) or physical (d.c. arc carrier distillation technique) separation of the major matrix, followed by the determination of trace metallic impurities in the raffinate, is a well accepted protocol in the nuclear industries to avoid spectral interferences from emissionrich matrices such as U, Pu, Zr, Th, etc. With ICP-AES analysis, the RSD is better (less than 5%), separation is time-consuming, involves handling of the materials which increases the chances of contamination, while the precision of the d.c. arc technique is 15-25%. Thus, there is a need to have an ICP-AES-based methodology where the analytes can be determined in a nuclear matrix at trace levels without requiring chemical separation. In this paper, an attempt was made to develop a method for the determination of trace constituents in a Zr matrix without separation by using the flexibility of a charge coupled device (CCD) detector for choosing additional interference-free analytical lines for Mn,
