Abstract A procedure is reported for the kinetic determination of thiocyanate based on the
catalytic effect of thiocyanate on oxidation of sodium azide by iodine at pH 5. The reaction is
monitored spectrophotometrically at 348 nm (absorption maximum of iodine). Calibration
curves for thiocyanate were linear in the range 1.0-2000 ng. ml− 1 with the detection limit of
0.3 ng. ml− 1 of thiocyanate. The method was applied for the determination of thiocyanate in
the water, serum and urine.
