F. Shamsa, Z. Hemmaceyan-Ettifak


A new spectrophotometric procedure forthe determination of cyanide is reported. The principle of the procedure is the bleaching of the cobalt - 0"- nitrozo-R - naphthol complex. The oragne colored complex between the cobalt and the reagent is formed in an alkaline pH and is extractabie by chloroform. Beer.s law is obeyed at 4-24 ug sodium cyanide. The effect of various cations and anions on the analytical procedure is also reported.
