Kelada-01 provides for rapid determination of total cyanide, acid dissociable cyanide, and thiocyanate in drinking water, wastewater, ambient water, and sludge, with minimal effects from interferences. Kelada-01 was developed by Dr. Nabih Kelada, and represents the culmination of years of cyanide chemistry research. The method uses a combined on-line ultraviolet (UV) irradiation and flash distillation system in place of classical manual cyanide distillation procedures to determine total cyanide. Under irradiation in a glass coil, strongly-bound complex cyanides (excluding thiocyanate) break down into free cyanide, which is separated from the sample matrix by distillation and is detected using an on-line colorimeter. By omitting UV-irradiation, acid dissociable cyanide complexes are broken down and determined. By replacing the glass irradiation coil with a quartz coil, thiocyanate can be determined.
