This paper discusses the characteristics of background absorption of seawater in platform graphite furnace AAS, including those of the wavelength and time, the evaporation behavior within graphite tube and the atomization condition, the matrix modifier and its amount. The relationship between background absorption and wavelength and the evaporation behavior of pure NaCl, MgCl, and MgSO4 is tested. The effects and mechanisms of background absorption of seawater in platform graphite furnace AAS are studied.
