ABSTRACT

Cyanide ion is highly toxic and life threatening. Cyanide is classified as various species. Along with understating of Cyanide complexes, there are several methods for analysis of Cyanide ion. Most of the regulatory compliance monitoring methods are based on Flow Injection Analysis (FIA) and colorimetry or Amperometric detection. These methods are challenged with interfering ions and requires significant sample preparation techniques before analysis.
In this presentation, deciphering the Cyanide ion(s) and their complexation species will be discussed. Also, straight forward Ion Chromatography method of analysis with “green chemistry” in perspective will be highlighted.
