Determination of Trace Resorcinol by Inhibition Kinetic Spectrophotometry

Yuan Zhao-ling

Abstract

A new inhibition kinetic spectrophtometric method for determination of Trace resorcinol was proposed.It is based on the inhibitory effect of resorcinol on the discoloration reaction between KIO_4 and cotton red catalyzed by Fe(Ⅲ) in dilute sulfuric acid solution.The optimum conditions and the kinetic parameters of this reaction were studied.The linear range of determ ination is 0.02～1.20 mg/L for resorcinol.The method was applied to the determination of resorcinol in water.
