TECH Brief 5 – Titrations for Weak Dissociable Cyanide in Water and Free Cyanide


No concentration should ever be reported as “0”. The limit of detection of free cyanide by titration should be determined and if the value obtained on a sample is less than the LOD, the result should be reported as “not detected” or <LOD. It is an important analysis to perform as cyanide is used for extraction of gold in mining and the extent that this anion may be reporting to environment needs to be known.
