Bromine content in polystyrene – optimization of the absorption solution for Combustion IC

Polystyrol is brominated to increase flame retardation. The brominated polystyrene finally consists of 25 to 35% of bromine. The determination of bromine by combustion ion chromatography (CIC) requires a specially optimized absorption solution to trap all bromide. This work shows the optimization of the absorption solution for high-bromine samples.
