1 Scope

This Part of YS/T 928 specifies the method for the determination of iron, calcium, magnesium,

copper, zinc, silicon, aluminum and sodium content in nickel cobalt manganese composite

hydrogenoxide.

This Part is applicable to the determination of iron, calcium, magnesium, copper, zinc, silicon,

aluminum and sodium content in nickel cobalt manganese composite hydrogenoxide. See Table

1 for the determination scope.

Table 1 -- Determination Scope

2 Method Summary

Use hydrochloric acid to dissolve the test portion and adopt an inductively coupled plasma

atomic emission spectrometer to directly conduct the determination. In accordance with the

working curve method, calculate the concentration of each element. Express the determination

results in mass fraction.

Element Determination Scope (w)/%

3 Reagents

All reagents used in this Part are of top-grade purity, and only pure water with an electrical

resistivity of not less than 18.2 Mohm - cm shall be used in the analysis.

300 mL beaker, slowly add 30 mL of nitric acid (3.4), use a watch glass to cover it; at a low

temperature, dissolve it and drive out nitrogen oxides, then, remove and cool it. Use water to

wash the watch glass and beaker wall. Transfer to a 1,000 mL volumetric flask, use water to

dilute to the scale and mix it well. 1 mL of this solution contains 200 µg of copper.

4 Instrument

In terms of the inductively coupled plasma atomic emission spectrometer, the spectral lines of

the various element are shown in Table 2; the working parameters of the instrument for sodium

determination are shown in Table 3; the working parameters of the instrument for the

determination of other elements are shown in Table 4.
