Scope: This document describes a method for the determination of calcium, hafnium, titanium, sodium, iron, chromium, cadmium, zinc, manganese, copper, nickel and lead in zirconium compounds by inductively coupled plasma atomic emission spectrometry. This document is applicable to the determination of calcium, hafnium, titanium, sodium, iron, chromium, cadmium, zinc, manganese, copper, nickel and lead in zirconium oxychloride, zirconium carbonate, zirconium sulfate and zirconium hydroxide. The measurement range is shown in Table 1. Table 1 Measuring range Element mass fraction %Ca 0.0005~0.050 Ti 0.0005~0.050 Fe 0.0005~0.050 Hf Na Cr Element mass fraction %Cd 0.0005~0.050 Mn 0.0005~0.050 0.100~2.000 Zn 0.0005~0.05 0 Cu 0.0005~0.050 Pb Ni 0.0005~ 0.050 0.0005~0.050 0.0005~0.050 0.0005~0.050
