Using ferric chloride as an oxidant, here, we investigated the leaching effect of low-nickel matte in a flow field produced by mechanical agitation. The factors affecting reaction, such stirring speed, time, particle size, and inert abrasive quartz sand, were studied. X-ray diffraction (XRD), fluorescence spectroscopy (XRF), laser size analyzer, optical microscopy (OM), scanning electron (SEM) ...

In this study, we analyzed the rickshaw (Owned by Daegu Modern History Museum) measuring each material. The purpose of study was to identify materials in modern cultural assets that utilize a variety complex way, and establish basic data for preservation management. Using portable X-ray fluorescence analyzers (P-XRF), species identification, fiber paint film analysis (microscope observation, SE...

This paper investigates the physical, chemical, and microstructural properties of two types natural sand; alluvial sands dune sand from El-Oued region in northeastern Algerian Sahara. Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), Fluorescence (XRF), Scanning electron microscopy (SEM/EDS), granulometry analysis have been performed. The FTIR XRD prove that consist high ...

Ghezeljeh montmorillonite nanoclay or “Geleh-Sar-Shoor” (means head-washing clay) used as a native adsorbent to extraction-preconcentration mercury ions from a variety of real water and fish samples have been investigated in a batch system followed by atomic absorption spectroscopy (AAS) with vapor generation accessory (VGA) system. The clay was characterized by using FT-IR, S...

This review supports an overview of selected high-performance fibers and functional fiber materials. A several properties applications is given. For materials fabrics, microscopic images taken by scanning electron microscopy (SEM) are presented. As well as this, dispersive spectroscopy (EDS) performed on the EDS spectra The features SEM discussed, especially with aim supporting people who worki...

Harmful elements (Pb, Se, Cd, etc.) in the soil samples were measured by X-ray fluorescence (XRF) method. We investigated the influence of the thickness of soil layer, the grain size of soils, and the water content in soils on XRF intensity. Since high-energy XRF such as Cd K was detected in deep inside of soils, a thickness of 10 mm was recommended. The soil sample with a small grain size gave...

X-ray diffraction (XRD), Scanning Electron Microscope-Energy Dispersive Spectroscopy (SEM-EDS), and Fourier Transform Infrared Spectroscopy (FT-IR), were applied to analyze the organic matrix of two Molluscan shells. The Mollusca shells are mineral structure and calcium carbonate crystallized as aragonite. The FT-IR spectra showed Alkyl Halide, Alkanes, Alcohols, Amides, Aromatic, and Hydroxyl ...
