A Review on Flow Injection Analysis for Indirect Determination of Cyanide ion in Environment by Flame Atomic Absorption Spectrometer

Among inorganic anions, cyanide is a potent toxicant in environment. Its species are historically known as the most harmful chemical pollutants of the environment to directly affect human health and some aquatics activity, even at minimum levels. Cyanide compounds are widely available with various chemical compositions and are applied in many industrial fields. This mini-review focused on the cyanide species and their measurement utilizing several analytical techniques. Detailed information on an indirectly determined cyanide species in various environmental samples was also reviewed using a flame atomic absorption spectrometer equipped with a flow injection system (FIA-FAAS). Obtained various analytical performance properties of an indirectly measured free cyanide ion in various samples using FAAS investigated from this study.
