title: The effect of trace levels of cyanide on the formation of mercury-iodide complexes.
abstract: The interference of trace levels of cyanide with the formation of iodo-mercury complexes is made the basis of a method of trace analysis for cyanide. The decrease in absorbance of the iodo-mercury complexes is a linear function of total cyanide concentration up to about 5 x 10(-5)M in 0.1M sodium hydroxide medium when the iodide and mercury total concentrations are 0.05 M and 3 x 10(-5)M respectively. Several cyano-mercury complexes are formed simultaneously, and quite a large fraction of the cyanide remains uncomplexed.
