Abstract
EPA Method Study 12, Cyanide in Water reports the results of a study by EMSL-Cincinnati for the parameters, Total Cyanide and Cyanides Amendable to Chlorination, present in water at microgram per liter levels. Four methods: pyridine-pyrazolone, pyridine-barbituric acid, electrode and Roberts-Jackson were used by 112 laboratories in Federal and State agencies, municipalities, universities, and the private/industrial sector. Sample concentrates were prepared in pairs with similar concentrations at each of three levels. Analysts diluted samples to volume with distilled and natural waters and analyzed them. Precision, accuracy, bias and the natural water interference were evaluated for each analytical method and comparisons were made between the four methods.
