| Abstract: | Using 0005 % methyl orange solution to concentrate bromine,free bromine in ambient air and industrial wastegas was determined with spectrophotometry,and the conditions of sampling,storage and optimum determination were studied.The results showed that the sampling efficiency of the method was more than 97 % with good linearity,accuracy and precision as well as high sensitivity.Calculated by 20 litres sample volume,the minimum detection concentration was 0026 %. |
