1 Method Summary

After sample digestion, the solution is atomized by air‑acetylene flame, and absorbance is measured at 285.2 nm. Within a specified concentration range, the absorbance of magnesium is proportional to its mass content, and quantification is realized via comparison against the standard calibration series.

2 Scope of Application

This method applies to the determination of magnesium content in sodium bicarbonate.
