Due to their non-destructive character, X-ray analytical methods are widespread in the field of archaeometry. In the present study, the use of synchrotron radiation induced X-ray fluorescence analysis (SR-XRF) is illustrated on three examples: a silver point drawing of Jan van Eyck, the Hiddensee Gold Treasure, and the Sky Disc of Nebra. The possibility to analyse large objects in normal atmosp...

Handheld X-ray fluorescence spectrometry (HH-XRF) has been established as the gold standard method for in-situ elemental determination in metals and alloys in the last 10 years. More than 5,000 analyzers are sold yearly worldwide for scrap metals sorting and positive material identification (PMI). PMI is a quality assurance tool consisting of the identification of alloy grades in various indust...

This paper presents the framework and results of analysis of the building materials used in traditional Chinese copper halls. The analysis of the Kunming copper hall (KCH) is presented as a typical example. First, the historical building structure of the KCH is investigated. Results of X-ray fluorescence (XRF) spectrometry are presented and analyzed according to the units of each building compo...

The usage of wastes of baggase would be admirable from environmental and solid waste management point of view. Thus, herein, this data set present a facile method for providing an adsorbent from mixture of bagasse-bentonite. The prepared adsorbent was applied to remove Cd2+ from aqueous solution. The characterization data of the adsorbent were analyzed using XRF and FTIR methods. The XRF test r...

A novel XRF sample preparation method was investigated to quantify the concentration of gallium in plutonium metal and minimize the possibility of contaminating the instrument with radioactive material. To prepare homogenous specimens and to add an internal standard, the plutonium must first be dissolved. The currently established method then entails removing the plutonium by chromatography and...

Heterogeneous catalysis performed in the liquid phase is an important type of catalytic process which is rarely studied in situ. Using microfocus X-ray fluorescence and X-ray diffraction computed tomography (μ-XRF-CT, μ-XRD-CT) in combination with X-ray absorption near-edge spectroscopy (XANES), we have determined the active state of a Mo-promoted Pt/C catalyst (NanoSelect) for the liquid-phase...

This paper presents the chemical and physical characterizations of SiO 2 and SiO 2 -CaO bioactive glasses incorporated with samarium atoms, produced by sol-gel synthesis. The objective is to provide biocompatible and biodegradable radioactive seeds as an alternative to be used in Brachytherapy for the treatment of prostate cancer. The glasses were produced and analyzed by X-ray fluorescence spe...

In mineral flotation the X-ray fluorescence (XRF) grade measurements of the slurries typically give the most important on-line information on the state of the flotation process. It has been shown that the visual and near-infrared (VNIR) reflectance spectrum measurements of certain mineral slurries can be used to complete the sparse XRF slurry content information. This study focuses on the chemo...

The aim of this research was to investigate the possibility of differentiation between black powder toners of similar polymer composition applying analytical methods: Fourier transform infrared spectrometry (FTIR) and X–ray fluorescence spectrometry (XRF). The studied materials were black powder toners of similar polymer composition sampled from the cartridges of 34 machines (31 models purchase...

Soil samples were collected from five provinces over China, including Beijing, Xinjiang, Heilongjiang, Yunnan, and Jiangsu. Heavy metal Cr, Zn, Pb and As in soils were analyzed by a portable X-ray fluorescence spectrometry (XRF). For predicating metal concentration in soils, a partial least square regression model (PLSR) was established. After cross-calibration, the correlation coefficients for...
