This method describes the collection of airborne bromine in the breathing zone of personnel in the workplace and the subsequent analysis by ion chromatography (IC). A calibrated personal sampling pump is used to draw a known volume of air through a midget fritted glass bubbler containing a sodium bicarbonate/sodium carbonate buffer solution. In the buffer collection solution, bromine disproportionates to bromide and bromate ions. Samples are analyzed with minimum sample preparation as these anions by ion chromatography.
