Abstract:A method for the determination of trace amount of thiocyanate has been described in this paper.It is based on the inhibition effect of thiocyanate on the oxidation of Rhodamine 6G by potassium bromate.The method is applicable to concentrations ranging from 0.4 to 32ng/mL.The Proposed method has been applied to determine trace thiocyanate in saliva,lake water and serum samples,and the results are satisfied.
Keywords:Thiocyanate determination  Rodamine 6G  Kinetic method  Fluorescence spectrophotometry
