摘要
The mechanism of combination of Flow injection(FIA)and double beam of photometry and testing technique,together with the color reaction condition of 2-(4-bromo-2-carboxy phenylazo)-7-(2,4-dimethyl phenylazo)-1,8-dihydroxynaphthalene-3,6-disulfonic acid reacting with Barium,and the application in the determination of Barium in sinter have been studied.The analyses speed was 130～140 times/h,the Sensitivity was 1.6 times of the ordinary photometric method,the dynamic concentration range of bariumn was 0～1.1μg·mL-1which was in consistent with a Lamber-beer law.The experimental results was satisfactory.

The analyses speed was 130 - 140 times/h,the Sensitivity was 1.6 times of the ordinary photometric method, the dynamic concentration range of bariumn was 0 - 1.1 μg · mL^-1 which was in consistent with a Lamber-beer law.
