Sažetak
The goal of this research was to determine the total concentrations of Ca, Fe, Cu and Mo in 43 referent soil samples by means of pXRF method and to determine the accuracy and precision of pXRF analyser. Results indicated that a Vanta handheld (portable) XRF analyser is capable of measuring Ca, Fe and Cu in restricted ranges of concentrations (2441 -219000 mg Ca/kg ; 3840 -59610 mg Fe/kg ; 25 -158 mg Cu/kg) with excellent (RPD 0-10 %) to good (RPD 10-25 %) accuracy and acceptable precision (RSD < 20 %) especially in clay soil samples. Molybdenum was not detected although several soil samples had concentrations of Mo higher than LOD (˃ 2 mg/kg). Along with extension of time analysis up to 120 seconds and same additional calibrations which will take in consideration matrix characteristics, pXRF will become an accurate and indispensable tool for nutrient and pollutant determination in soils because of numerus advantages including speed and low cost analysis.
