Scope
This standard specifies the method for determining nitrate nitrogen (NO3--N) and nitrite nitrogen (NO2--N) in coking wastewater using the reduction-neutralization titration method with Dai's alloy. This standard is applicable to the determination of nitrate nitrogen (NO3--N) and nitrite nitrogen (NO2--N) in coking wastewater. The measurement range (mass concentration): nitrate nitrogen 1.0 mg/L to 150.0 mg/L, nitrite nitrogen 1.0 mg/L to 100.0 mg/L.
