The Simultaneous Arsenic, Antimony, and Selenium Determination in Water Samples by Batch Hydride Generation Atomic Absorption Spectrometry

The purpose of this paper is to present a procedure for the simultaneous determination of metalloids: arsenic, antimony, and selenium. Hydride generation was provided in a reaction vessel connected with the atomic absorption spectrometer (AAS) in a fast sequential mode. Two different types of water samples were used while developing the application: seawater and groundwater. The methodology of liquid samples analysis was developed with detection limits of 0.05, 0.03, and 0.06 ng · mL−1 for arsenic, antimony, and selenium, respectively, in 10 mL samples. This methodology was used to determine arsenic, antimony, and selenium in natural water samples.
