Abstract:
OBJECTIVETo establish a spectrophotometric determination method of bromine in the air of workplace.
METHODSBromine in the air of workplace was absorbed by methyl orange solution, then determined by spectrophotometry.
RESULTSThe 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%.
CONCLUSIONThe method is available for the determination of bromine in the air of workplace.
