Determination of inorganic arsenic species As(III) and As(V) by high performance liquid chromatography with hydride generation atomic absorption spectrometry detection

Abstract

The paper presents the principles and advantages of a technique combining high performance liquid chromatography and hydride generation atomic absorption spectrometry (HPLC-HGAAS) applied to speciation analysis of inorganic species of arsenic As(III) and As(V) in ground water samples. With separation of the arsenic species on an ion-exchange column in the chromatographic system and their detection by the hydride generation atomic absorption spectrometry, the separation of the analytical signals of the arsenic species was excellent at the limits of determination of 1.5 ng/ml As(III) and 2.2 ng/ml As(V) and RSD of 4.3% and 7.8% for the concentration of 25 ng/ml. The hyphenated technique has been applied for determination of arsenic in polluted ground water in the course of the study on migration of micropollutants. For total arsenic concentration two independent methods: HGICP-OES and HGAAS were used for comparison of results of real samples analysis.

Luminescent Silole Nanoparticles as Chemoselective Sensors for Cr(VI)

“…For chromium, it would be advantageous to be able to distinguish harmful Cr(VI) from benign Cr(III). There are currently several physical detection methods used to identify the presence of chromium and arsenic in aqueous media, including high performance liquid chromatography coupled with atomic absorption spectrometry, − fiber optic wave sensors, ion chromatography, − inductively coupled plasma-MS, , electrochemical processes, , and electron capture GC. , Methods using luminescence quenching for detecting chromate have also been used. These include bacterial sensors with detection limits as low as 2.6 ppb …”

Detection of Arsenic(V) by Fluorescence Sensing Based on Chlorin e6-Copper Ion

“…Currently, there are many techniques available for copper and arsenic detection, such as atomic absorption/emission spectrometry (AAS/AES) [ 10 , 11 , 12 ], atomic fluorescence spectroscopy (AFS) [ 13 , 14 ], X-ray fluorescence spectroscopy (XRF) [ 15 , 16 ], inductively coupled plasma–mass spectrometry (ICP–MS) [ 17 , 18 ], electrochemistry [ 19 , 20 , 21 ], ultraviolet–visible absorption spectrometry (UV–Vis)/colorimetry [ 22 , 23 , 24 , 25 ], and fluorescence spectroscopy [ 26 , 27 , 28 , 29 ], etc. These methods have their characteristics and advantages for testing different environmental samples, but the drawbacks of some methods, such as AAS/AES and ICP–MS, which require expensive and large instruments and specialized operators, limit their applications [ 27 , 30 ].…”
