摘要: A method for quantitatively determining the cyanide content of aqueous solution containing aldehydes and/or ketones as a measure of the sum of the free cyanide and cyanohydrin content. The method comprises converting cyanohydrin to free cyanide and then determining the free cyanide content of the solution.
