Abstract

A new indirect atomic absorption spectrophotometric method for the determination of thiocyanate ion in water is proposed. The method is based on the extraction of the ion-pairs formed between thiocyanate ion and thiourea-copper(I) complex with methyl isobutyl ketone. Under the optimum conditions established, thiocyanate ion ranging from 0.04 μg/ml to 2 μg/ml in water could be determined. The method was applied to the determination of thiocyanate ion in human saliva.
