The preparation, certification, and characterization of two new biological certified reference materials for inorganic trace analysis have been presented. They are based on different varieties tobacco leaves, namely, Oriental Basma Tobacco Leaves (INCT-OBTL-5), grown in Greece, Polish Virginia (INCT-PVTL-6), Poland. Certification the was statistical evaluation results obtained a worldwide interlaboratory comparison, which 87 laboratories from 18 countries participated, providing 2568...
With advancements in hardware and software, non-destructive radiometric analytical methods have become popular a wide range of applications. A typical case is the study leaching process metals from mineral ores mine tailings. The objective current was to develop method based on neutron activation analysis (NAA), particular, delayed gamma (DGNAA), monitor Mn Zn Ti ore, Cu tailings, Zn-Pb DGNAA performed using source: deuterium-tritium (D-T) generator for MARIA research nuclear reactor Zn....
This article presents final technical and economical results of the comprehensive control rehabilitation project done for ammonia synthesis plant at JP Nawozy, GA ZAK S.A. The included following activities: review existing philosophies instrumentation infrastructure, design implementation new loop templates, tuning revised controls over entire installation. These activities improved installation operation with much more reliable repeatable dynamic responses. Simultaneously, overall...
Abstract Scanning electron microscopy with X-ray microanalyses (SEM-EDX) was used for a technological study of silver jewellery from three hoards found in Poland. The assemblage consists 26 artefacts the period formation first Polish state (900–1039 AD) and can be divided into groups: West Slavic, post-Moravian Scandinavian. Research results provide information concerning techniques granulation ornament provenance raw silver. Elemental composition changes are manifested mainly by different...
Solvent extraction of metals from Ti ore was investigated with a view enhancing yields by changing the concentration ligands, rate mixing, pH, and temperature solution. Norwegian leached 5M HNO3 alongside 10% ascorbic acid to obtain pregnant solution containing transition some rare earth elements (REEs). Part Two study will address recovery REEs in ore. The elemental analysis solid aqueous samples done two models total reflection X-ray fluorescence spectrometers (S2 PICOFOX, Bruker...
An interdisciplinary study of metallic objects from selected archaeological sites in Poland was performed.The aim the project to obtain information about chemical composition and structural changes objects.Furthermore, research results provided technological process which used manufacture artifacts.The materials had a non-and micro-invasive character is very important this type investigation.The main experimental tools were particle-induced X-ray emission supplemented with nuclear reaction...
Inductively coupled plasma mass spectrometry (ICP-MS) and instrumental neutron activation analysis (INAA) were applied to study the elemental content of coal combustion residues. Both methods’ analytical applicability suitability for this type material described in detail. A certified reference material, fine fly ash (CTA-FFA-1), was used examine capabilities validation both methods. comparison allowed modification procedures these materials (previously elaborated Institute Nuclear Chemistry...
A unique shield grip decorated with openwork rivet plates was found in a Roman Period cemetery of the Przeworsk culture Czersk, Central Poland. The artefact underwent specialist analyses use various techniques order to reveal its silvering technology. Several were considered as most probable: foil silvering, mercury and silver plating. number complementary analytical methods such laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), scanning electron microscopy...
Modern archaeology makes use of analytical methods in order to answer questions about deposit and technological provenience artefacts.This paper discusses selected the most interesting, results obtained during completion a research project which focuses on silver from 10th 11th centuries Poland.In total, 200 artefacts known Polish hoards (found Kalisz-Dobrzec, Nowa Obra, Wolsztyn District, Zalesie, Olsztyn Słuszków Jastrzębniki, Kalisz Kalisz-Rajsków Stojkowo, Kołobrzeg District Naruszewo,...
High temperature gas-cooled reactors have recently gained importance as a source of electricity and process heat. Nuclear fuel used in these consists TRISO (TRiple coated ISOtropic) particles, where spherical grains UO2 or UC2 UCO kernel are covered with four successive layers consisting pyrolytic carbon silicon carbide. Of great is the chemical purity reagents substances for production particles. Analytical techniques ensuring determination elements at trace levels inductively coupled...
Abstract Three new reference materials: MODAS-3 Herring Tissue (M-3 HerTis), MODAS-4 Cormorant (M-4 CormTis), and MODAS-5 Cod (M-5 CodTis) were prepared certified on the basis of results a worldwide intercomparison exercise. Independently our proven method establishing information values, content several essential toxic elements was additionally determined by use ratio primary measurement procedures (definitive methods) based radiochemical neutron activation analysis (RNAA) in case As, Cd,...
