Standard Test Method for Free Cyanide and Aquatic Free Cyanide with Flow Injection Analysis (FIA) Utilizing Gas Diffusion Separation 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 wastes and surface waters.4

5.2 It is useful to determine the aquatic free cyanide to establish an index of toxicity when a wastewater is introduced into the natural environment at a given pH and temperature.

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

5.4 Free cyanide measured using this test method is applicable for implementation of the International Cyanide Code Guidance in accordance with Guide D7728.
