The effect of hydrogen gas on the plasma and its influence on acid interferences in plasma atomic emission spectrometry was studied. The study was performed with HCl and HNO(3) in the concentration range of 0-2 mol l(-1). Vanadium and magnesium were used as test elements, the study was extended to other several elements. The effects of hydrogen gas on the plasma were studied by measuring excita...

In two configurations, a solid-state acousto-optic (AO) deflector or modulator is mounted in a 0.5 m monochromator for background correction with inductively coupled plasma atomic emission spectrometry (ICP-AES). A fused silica acousto-optic modulator (AOM) is used in the ultraviolet (UV) spectral region applications while a glass AO deflector (AOD) is used for the visible (VIS) region. The sys...

An inductively coupled plasma atomic emission spectrometry (ICP-AES) method was developed for the determination of phosphorus in fertilizers. Total phosphorus, direct extraction available phosphorus (EDTA), and water-soluble phosphorus, reported as phosphorus pentoxide (P205), in 15 Magruder check fertilizers were measured by ICP-AES, and the results were compared with those obtained by the AOA...

This paper describes a direct method for arsenic determination and speciation in wine samples by hydride atomic emission spectrometry with inductively coupled plasma (ICP-AES). Optimization of the method included investigation of several parameters that impact the intensity of spectral lines: concentration of reaction media (hydrochloric acid), reduction reagent concentration (sodium borhydride...

A high content of heavy metals in the soil and plants a magnesite mining area might cause serious damage to environment can be threat health surrounding population. This paper presents results research that focused on analyzing metal dumping grounds factory Jelšava-Lubeník (Slovakia). The analysis (X-ray fluorescence spectrometry, atomic absorption spectrometry), (inductively coupled plasma mas...
