A B S T R A C T According to the invention, cyanide concentrations of from about 0.001 to 5 mg cyanide/1 are continuously determined colorimetrically by the known cyanide-picric acid color reaction. The solution containing free cyanide and/or cyanide releasable from cyano complexes is reacted for 1 to 60 minutes at 50 to 120°C in a gastight closed system in the presence of chelating agents to form the color complex and the extinction value is measured by spectral photometry. The process avoids the extraction step hitherto necessary for cyanide concentrations below 0.2 mg CN/1 and errors attributable to HCN- outgassing losses, is simple to handler largely immune to interference and suitable for the continuous monitoring of wastewater streams or for the control of cyanide detoxification processes.
