          1. Method Overview The sample is dissolved by heating in a quartz beaker using a mixed acid of sulfuric acid and phosphoric acid. An air-acetylene flame is employed, and the absorbance of sodium oxide is measured at a wavelength of 589.0 nm using an atomic absorption spectrometer. Within a certain concentration range, the absorbance of sodium is proportional to its content, and quantitative determination is performed by comparison with a standard series. 2.
