Standard Test Method for Total Cyanide by Segmented Flow Injection Analysis, In-Line Ultraviolet Digestion and Amperometric Detection

Importancia y uso:

5.1 Cyanide and hydrogen cyanide are highly toxic. Regulations have been established to require the monitoring of cyanide in industrial and domestic wastewaters and surface waters.4

5.2 This test method is applicable for natural water, saline waters, and wastewater effluent.

5.3 This test method may be used for process control in wastewater treatment facilities.

5.4 The spot test outlined in Test Methods D2036, Annex A1, can be used to detect cyanide and thiocyanate in water or wastewater, and to approximate its concentration.
