摘要

A simple, selective and sensitive ion-chromatography method was investigated for simultaneously determining silicic acid, Ca²⁺, Mg²⁺, Al³⁺ and anions (Cl^- and NO₃^-)in real samples. It involved a single-column ion-chromatograph with sodium hydroxide-methanol-water eluent and conductometric detection. Cations were converted to complex anions by adding EDTA to the sample solution. A set of well-defined peaks of silicic acid, Ca²⁺, Mg²⁺, Al³⁺, Cl^- and NO₃^- were obtained. Detection limits using 3.3σ (σ = standard deviation of blank solution) were 1.25 × 10^-6 M for H₃SiO₄^-, 1.32 × 10^-6 M for Ca²⁺, 1.28 × 10^-6 M for Mg²⁺, 1.33 × 10^- 6 M for Al³⁺, 1.31 × 10^-6 M for Cl^- and 1.24 × 10^-6 M for NO₃^-. The method was successfully applied to analysis of mineral water and composite tablets.
