Scope
Main technical content: This standard specifies the gas-phase molecular absorption spectrometry method for determining the permanganate index in water. This standard is applicable to the determination of the permanganate index in surface water, groundwater, and domestic drinking water. The detection limit of this standard is 0.10 mg/L, and the measurement range is 0.40 to 5.00 mg/L (calculated in terms of O2). When the sample concentration exceeds the measurement range, it shall be measured after dilution.
