本文介绍了一种改进的碘量法，用已知砷量的2%NBKI吸收液测定10 ml水样。臭氧含量从0.5到65毫克O3/升进行了测定。也可以测量高臭氧浓度用于发生器校准。该方法得到的结果与硼酸法无显著差异，但适用于改良的标准方法程序。碘的挥发性已完全消除。稳定样品不会使取样和最终滴定之间的时间成为关键。
Abstract A modified iodometric procedure using an absorbing solution of 2% NBKI with a known amount of As(III) is described for 10 ml aqueous samples. Ozone contents from 0.5 to 65 mg O3/I were determined. High ozone concentrations can also be measured for generator calibration. This method gives results which are not significantly different than a boric acid method but are for a modified standard methods procedure. Volatility of iodine has been completely eliminated. Stabilized samples do not make the time between sampling and final titration critical.
