Název v původním jazyce

Infrared laser ablation study of pressed soil pellets with inductively coupled plasma atomic emission spectrometry

Popis výsledku v původním jazyce

Potential of infrared laser ablation (LA) coupled with ICP-AES as a technique suitable for determination of trace elements (Zn, Cu, Ni, Cr, and V) in agricultural soils was studied. Operating parameters such as laser beam energy, laser beam focusing withrespect to the sample surface, and velocity of the sample translation in the plane perpendicular to the laser beam were optimized. Soil samples were mixed with powdered Ag as a binder, and an internal standard (GeO2), and pressed into pellets. Calibration samples were prepared by adding known amounts of oxides of elements of interest into soils of known elemental composition and then processed in the same way as the analyzed samples. Calibration curves were found to be linear at least up to several hundreds of mg/kg for the elements of interest. The elemental contents obtained using LA-ICP-AES were compared with those obtained by analysis using wet chemistry followed by ICP-AES with pneumatic nebulization (PN). The results were in good
