A Comparison of Recent Analytical Methods for Analysis of Arsenic

Abstract

Arsenic is one of the known toxic elements to human’s life. Never the less, the level of toxicity relies on the classification of chemical species of arsenic as organic or inorganic which being a big concern in industrial and environmental chemistry. different separation methods as HPLC or IC has been coupled to either ICP-MS or ICP–OES in order to increase sensitivity of determining As(III) and As(V), while for determining As(III) and total As need a chemical reduction of As(V) before utilise voltammetry .with the aim of having best technique to trace elements levels especially toxic elements , some aspects must to be advanced such as reducing chemical and physical interferences , high sensitivity , low LOD and LOQ , less time consuming , more accurate than conventional techniques and less cost equipment. Other methods as bio-components, ETAA, (INAA) and AAS have been showing promising future for analysis techniques.
