Abstract: A kinetic spectrophotometric method for rapid measurement of thiocyanate in
serum, urine and sewage water with no need for removed of interfering substances is
described. The method is based on the inhibitory effect of thiocyanate on the oxidation of
pyrogallol red by bromate and nitrite which is monitored at 467nm. The variables affecting
the rate of the reaction were investigated and the optimum conditions were established.
Thiocyanate can be measured in the range of 0.10-0.500 mg/mL with a limit of detection of ...
