“…For the estimation of thorium, 283.231 nm, 283.730 nm and 401.913 nm analytical lines were chosen. 67,68 The detection limit of 401.913 nm line was found to be one order better (0.003 μg mL −1 ), compared to the other two analytical lines. This line was also shown three times more sensitive compared to the other two lines.…”

“…Due to the high excitation temperature of the plasma, more emission lines are available for the determination but some may lead to spectral interference. Mainly the nuclear material matrix elements are multi-electronic and have emission-rich spectra; hence, they are expected to show severe spectral interference while determining the analytes in these matrices especially at the trace level (21)(22)(23)(24)(25). Therefore, either incorporation of correction factors for spectral interference or chemical separation of the major matrix are the two strategies adopted in an ICP-AES-based methodology.…”

Methodologies have been developed for the chemical quality control of zircon mineral by EDXRF and D.C.Arc carrier distillation technique. EDXRF technique was found to be preferred for major and minor constituents including non‐metal analytes, while D.C.Arc carrier distillation OES was found to be good for minor and trace metallic constituents including low Z elements. A comparative evaluation of the analytical performance (detection limit, sensitivity, precision, linear dynamic range) was performed. A multipoint standardization was carried out using the base material of 1 : 1 SiO2 : ZrO2 powder mixture to establish calibration curves for the analytes after identification of interference free and the best performed emission and X‐ray analytical lines. In zircon sample, Si, Zr and Y were found to be present as major constituent, with Ga, Ca, Ru, Rh, Fe, Mn, Mg, I, S as minor and Zn, Cr, Sn, Li as trace constituents. The total uncertainty of the EDXRF measurements was evaluated. The statistical t‐test analysis was carried out for 10 degrees of freedom with 95 % confidence interval. The experimentally obtained t‐values were found to be lower compared to the corresponding tcri value revealing the reliability of the measurements. Elemental distributions of the analytes were also investigated using five different zircon samples.
