Abstract

Abstract : A simple and accurate ion chromatography (IC) method with pulsed amperometric detection (PAD) was proposed for the determination of cyanide ion in urine, sweat, and saliva samples. The sample pretreatment relies on alkaline digestion and application of Dionex OnGuard II H cartridge. Under the optimized conditions, the method showed good linearity in the range of 1–100 μ g/L for urine, 5–100 μ g/L for saliva, and 3–100 μ g/L for sweat samples with determination coefficients ( R ) > 0.992 . Low detection limits (LODs) in the range of 1.8 μ g/L, 5.1 μ g/L, and 5.8 μ g/L for urine, saliva, and sweat samples, respectively, and good repeatability (CV < 3%, n = 3 ) were obtained. The proposed method has been successfully applied to the analysis of human biological samples.
