Investigation of Poor Analytical Recovery Using Borosilicate Glass Containers in Selenium Determination by Atomic Absorption Spectrometry with Hydride Generation

Determination of trace selenium in urine by derivative hydride generation atomic absorption spectrometry.

Interferences study for Selenium determination using of on Liquid Nitrogen Trap Hydride generation atomic absorption Spectrometry

A method has been developd determine selenium by hydride generation atomic absorption using nitrogen trapping technique. A series of experiments was performed to obtain the optimum condition. The results show that this method has the advantage of being sensitive, accurate, rapid and simple. Transition metal and other hydride forming elements interferences on the determination of selenium was st...

Determination of selenium in Teucrium species by hydride generation atomic absorption spectrometry.

Hydride generation atomic absorption spectrometry (HGAAS) was applied for determination of selenium content in dried aerial parts of wild and cultivated Teucrium species (Lamiaceae) growing in Croatia: T. arduini L., T. chamaedrys L., T. flavum L., T. montanum L., T. polium L., and T. scordium L. subsp. scordioides Schreb. Special attention was paid to the wet oxidation procedure for the sample...

On-line hyphenation of hydride generation with in situ trapping flame atomic absorption spectrometry for arsenic and selenium determination.

The analytical performances of coupled hydride generation, integrated atom trap (HG-IAT) atomizer flame atomic absorption spectrometry (FAAS) systems were evaluated for determination of As and Se in biological and environmental reference materials. Arsenic and Se hydrides are atomized in air-acetylene flame-heated IAT. A new design of HG-IAT-FAAS hyphenated technique that would exceed the opera...

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...
