Study on the Determination of Trace Bromine by Minus Catalytic Kinetic Spectrophotometry

ZHANG Da-lun *,ZHAO Chun-yang, WANG Jian-ying (Department of Pharmaceutics, Wuhan Chemical Engineering Institute, Wuhan ,430073)  
A new method for the determination of trace bromine ion is described. The method is based on its minus catalytic effect upon KBrO 3 oxidize methyl orange. The molar absorption coefficient is 1 0×10 6 L·mol -1·cm -1. The linar range of the determination for bromine is 0.5 ~ 1.8 ng/mL.The method has been used for the determination of trace bromine in well water and salt with satisfactory results.
