- Scope
- This standard specifies a flow injection-spectrophotometric method for the determination of cyanide in water. This standard is applicable to the determination of cyanide in surface water, groundwater, domestic sewage and industrial wastewater. When the detection light path is 10mm, the detection limit of cyanide in water by the isonicotinic acid-barbituric acid method is 0.001mg/L, and the detection range is 0.004mg/L~0.10mg/L; the pyridine-barbituric acid method The detection limit of cyanide in water is 0.002mg/L, and the detection range is 0.008 mg/L~0.50mg/L.
