ASSAY FOR CYANIDE BY TITRATION WITH SILVER

2018-2-5  The standard solution of silver nitrate is made by dissolving 13.076 grams of silver nitrate in distilled water and diluting to 1 litre; 100 c.c. of such a solution are equivalent to 1 gram of potassium cyanide. The titration is performed in the usual way, running the standard solution of silver nitrate into a solution containing a known weight or volume of the material containing the cyanide.

Free cyanide analysis by silver nitrate titration with ...

Abstract In cyanidation process, the free cyanide concentration is the main variable that controls the efficiency of the process, and the plant operators determine it by silver nitrate titration. If sulfide ion is present in the solution the free cyanide concentration cannot be determined by titration as the silver added in the titration reacts with the sulfide ion to form a black solid ...
