This standard specifies a method for the determination of lead content in industrial wastewater of nitroglycerin series explosives by Oscillopolarography. The applicable lead measurement range is 0.10~ 10.0 mg/L, and the minimum detection concentration is 0.02 mg/L. Since dinitro toluene in wastewater can interfere with the determination of lead reduction peak, this method uses lead oxidation peak for measurement. When treating Miscellaneous type industrial wastewater, the suitable polarographic peak type can be selected according to the specific water quality conditions for determination. This standard has high Sensitivity and accuracy for the detection of lead, and is suitable for environmental monitoring and industrial wastewater treatment.
