It is clearly established that the toxicity and bioavailability were depend on arsenic speciation.

A novel method for the on-line determination of arsenic species by ion chromatography coupled with atomic fluorescence spectrometry using a home-made bi-anode electrochemical hydride generator as an interface(IC-BAECHG-AFS)has been investigated.

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

The Study of Arsenic Species in Seaweeds and the Effect of Processing;

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.
