A fast screening method for determination of inorganic arsenic in marine samples was developed. This method is based on selective hydride generationanddetectionby inductively coupled plasma mass spectrometry.
Using a high concentration of hydrochloric acid together with hydrogen peroxide for hydride generation leads to selective conversion of inorganic arsenic species into arsane. The accuracy of this method was verified by comparative analyse by high performance liquid chromatography coupled with hydride generation and atomic fluorescence detection.
