A modified analysis method based on the determination of ozone—indigo disulphonate spectrophotometer(GB/T 15437-1995) in gas phase has been developed to detect the concentration of ozone in liquid phase. An analytical condition of λmax=612~615 nm,ε=20 000 L/, pH 2 is obtained by the titration of indigo disulphonate. Compared with potassium iodide method,it shows a higher precision and accuracy,CV<3.0%. The results also prove that blank experiment will bring about 5.0%systematic error.
