The content of halogen in electrical and electronic products was determined by ion chromatography with oxygen bomb combustion(OBC). The results showed that the concentration of four ions (F–,Cl–,Br–,I–) was linear with peak area with correlation coefficent more than 0.999. The recovery of four ions was 90% –110%,and the relative standard deviation of testing results was less than 5.0% (n=6). The method is rapid and accurate, it can be used for the determination of halogen in electronic and electrical products.
