Two analytical reagent grade standard solutions are required. The first is a 50 + 0.5-g/l sodium cyanide solution (1 g/l sodium hydroxide for stabiliza-tion), and the second is a 17 + 0.1-g/l silver nitrate titrant solution. These two solutions are prepared and standardized as described in References 2 and 3.

HYDROGEN CYANIDE (AC) : Systemic Agent - CDC

UN 1051, hydrogen cyanide (AC), >20% solution or anhydrous, is extremely flammable. UN 1051 may be ignited by heat, sparks, or flames. UN 1614, hydrogen cyanide (AC), stabilized and UN 3294, hydrogen cyanide (AC) solution in alcohol, are highly flammable. UN 1614 and UN 3294 will be easily ignited by heat, sparks, or flames.

Cyanide measurement by silver nitrate titration ...

Rhodanine titration of the zinc cyanide solutions at the various pH values found that the measured cyanide was independent of pH and equivalent to the total cyanide in solution. This indicates that the cyanide ions complexed with zinc are only weakly bound and are easily released to complex with silver ions.

ANALYSIS OF CYANIDE - c.ymcdn

Cyanide levels are tested in drinking and wastewater. According to the USEPA, the only method more challenging is that for Oil and Grease. Cyanide chemistry is complex and matrix interferences can be very hard to identify and alleviate. Treating for an interference can make things worse. Some interferences have no known mitigation.
