Scope

The sample is decomposed with hydrochloric acid and nitric 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
324.7 nm.
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.
