Study on arsenic level in ground water of Delhi using hydride generator accessory coupled with atomic absorption spectrophotometer

Ultra-trace level detection of arsenic and selenium using a commercially available hydride generator with atomic-absorption detection

Speciation of Arsenic(III)/Arsenic(V) and Selenium(IV)/Selenium(VI) Using Coupled Ion Chromatography– Hydride Generation Atomic Absorption Spectrometry

Simple analytical methods have been developed to speciate inorganic As and Se in the microgram per liter range using coupled ion chromatography–hydride generation atomic absorption spectrometry. Because of the differences in toxicity and adsorption behavior, determinations of the redox states arsenite, As(III), and arsenate, As(V), and selenite, Se(IV), and selenate, Se(VI), are important. Anio...

Quantifying uncertainty in the measurement of arsenic in suspended particulate matter by Atomic Absorption Spectrometry with hydride generator

Arsenic is the toxic element, which creates several problems in human being specially when inhaled through air. So the accurate and precise measurement of arsenic in suspended particulate matter (SPM) is of prime importance as it gives information about the level of toxicity in the environment, and preventive measures could be taken in the effective areas. Quality assurance is equally important...

Determination of arsenic(III) and total inorganic arsenic in water samples using an on-line sequential insertion system and hydride generation atomic absorption spectrometry

A simple and robust on-line sequential insertion system coupled with hydride generation atomic absorption spectrometry (HG-AAS) was developed, for selective As(III) and total inorganic arsenic determination without pre-reduction step. The proposed manifold, which is employing an integrated reaction chamber/gas–liquid separator (RC-GLS), is characterized by the ability of the successful managing...
