Scope

The sample is decomposed with appropriate mixed acid, perchloric acid is
added to evaporate it to produce smoke, AND water is used to dissolve the salt.
The sample solution is sprayed into the air-acetylene flame, and the copper
hollow cathode lamp is used as the light source. The atomic absorption
spectrophotometer is used to measure the absorbance at the wavelength of
232.0nm.
To eliminate matrix effects, when drawing the calibration curve, it shall add the
iron the amount of which is similar to that of the sample solution.
