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.
