title: [Application of indigo disulphonate spectrophotometry on the determination of ozone in indoor air].
abstract: Spectrophotometric determination of ozone in indoor air by using indigo disulphonate was investigated. The results showed that the average recovery of ozone was 99% and the relative standard deviation was 2.3% when the concentration of indoor ozone was in the range of 0.2-1.0 microgram/ml. The lowest detection concentration was 0.009 mg/m3 (sampling 20 L) when the range of determination was 0.18-10.0 mg/10 ml.
