1 Scope

This section specifies the determination by inductively coupled plasma atomic bismuth tellurium, aluminum, lead, iron, selenium, copper, magnesium, sodium, arsenic emission spectrum method.

This section applies to multi-element tellurium, bismuth, aluminum, lead, iron, selenium, copper, magnesium, sodium, simultaneous determination of arsenic content, but also for one Determination of the elements, or any combination of several elements. Determination of the range in Table 1.

Table 1 element Measuring range

Element measurement range /% Bi, Al, Cu, Mg, Na, As 0.0005 ~ 0.005 Pb, Fe 0.0005 ~ 0.010 Se 0.0005 ~ 0.060

2 Principle of the method

The sample is dissolved in acid, in an acidic medium, in inductively coupled plasma atomic emission spectrometer, for each element corresponding to the wavelength Measuring the emission intensity, calculate the mass fraction of each test element according to the working curve.

3 Reagents

Unless otherwise indicated in the analysis using only the reagents and confirmed analytically pure deionized water.
