摘　　要：建立了快速简便、灵敏的测定室内空气中臭氧的方法——靛蓝二磺酸钠分光光度法。研究结果表明 :当室内空气中臭氧含量在 0 .2～ 1.0 μg/ml范围时 ,平均回收率为 99% ,相对标准差为 2 .3% ;测定范围在0 .18～ 10 .0μg/10 m l时 ,最低检出浓度为 0 .0 0 9mg/m3(采样 2 0 L )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 μg/ml. The lowest detection concentration was 0 009mg/m 3(sampling 20L) when the range of determination was 0 18～10 0 mg/10ml.
