| Abstract: | A method.of oxygen bomb combustion - by Ion Chromatography was applied to the determination of iodine content in Spirulina. The Metrosep A Supp 4column, 1.Smmol/L Na2CO3 ＋1.7mmol/L NaHCO3 shower lotion, flow rate lmL/min, conductivity detector was selected. The sample was treated by oxygen bomb combustion, then absorbed by the （0.714g NaHCO3 ＋0.954g Na2CO3 ） / L absorption liquid, filtered after constant volume for test. Used for analyzing the spirulina sample, the recovery was 102%. This method is rapid, simple and sensitive. Sample measurement result is satisfactory. |
