摘要：

A postcolumn liquid chromatographic procedure for the determination of cyanide with fluorimetric detection was developed. The method is based on both the separation of cyanide ion in the ion-exclusion mode and the postcolumn fluorescence derivatization of cyanide ion with omicron-phthalaldehyde or naphthalenedicarboxaldehyde in the presence of amino acid. Various parameters such as the kind of amino acid, pH of the reagent buffer and concentration of the sodium salt of EDTA were optimized to provide quantitative conversion of cyanide ion to the fluorescent derivative.
