Scope

This document specifies the continuous flow analysis spectrophotometric method for the determination of cyanide in water.
This document is applicable to the determination of cyanide in surface water, groundwater, and drinking water. Municipal wastewater and industrial wastewater can be used as reference for application.
When the optical path length of the detection cell is 50 mm, the detection limit of this method is 0.000 5 mg/L, and the measurement range is 0.002 mg/L to 0.500 mg/L.
