ABSTRACT
<p><b>OBJECTIVE</b>To establish a spectrophotometric determination method of bromine in the air of workplace.</p><p><b>METHODS</b>Bromine in the air of workplace was absorbed by methyl orange solution, then determined by spectrophotometry.</p><p><b>RESULTS</b>The range of the determination was 0.2 to 2.8 microg/ml, the linear equation was Y=0.0427X-0.0092, r=0.9996. The detection limit was 0.2 microg/ml. The minimum detectable concentration was 0.27 mg/m(3) for 7.5 L air sample. The relative standard deviations covered the range of 1.1% approximately 3.7%. The recovery rate was in the range of 93.6% to 97.2%. The sampling efficiency ranged from 93.5% to 100.0%.</p><p><b>CONCLUSION</b>The method is available for the determination of bromine in the air of workplace.</p>
