Paper Abstract
Chemical speciation is defined as the determination of the concentration of an analyte (e.g., Chromium or Cr) in the oxidation state in which it exists in the environment (e.g., sea water). Determinations of the concentration of different Cr-species is important due to toxicity differences of the different oxidation states of Cr. For example, Cr(III) is regarded as generally non-toxic and is considered as an essential micro-nutrient. But Cr(VI) is considered as carcinogenic. In this paper, speciation methods for Cr in sea water samples using large scale plasmas, such as an ICP (Inductively Coupled Plasma) and steps taken toward using a microplasma are described.
