This method can be used for the analysis of arsenic speciation in environmental water.

This article briefly summarizes the recent developments in arsenic speciation analysis and discusses the benefits and defects of the various speciation techniques as applied to studies of environmental and toxicological chemistry of arsenic.

Sample pretreatment techniques for arsenic speciation;

Although there are many methods for arsenic speciation, UV, a routine detector, had low sensitivity while ICP-MS was not common used because of its expensive cost.

Determination of inorganic arsenic form by half differential anode stripping voltammetry;
