        1. Method Overview After the sample is digested, it is atomized by the flame of an atomic absorption spectrometer, and the absorbance is measured at a wavelength of 766.5 nm. Within a certain concentration range, the absorbance value is proportional to the potassium content, and quantification is performed by comparison with a standard series. 2.
