Determination of Sulfur in Plant Using a High-Resolution Continuum Source Atomic Absorption Spectrometer
Yu WANG, and Jia-xi LI
A method for the analysis of sulfur (S) in plant by molecular absorption of carbon monosulfide (CS) using a high-resolution continuum source atomic absorption spectrometer (CS AAS) with a fuel-rich air/acetylene flame has been devised. The strong CS absorption band was found around 258 nm. The half-widths of some absor
