2018年2月15日 · Recently we started research on iron mineral formation from ferrous iron solutions, aiming to develop a new microbiological method for iron removal from groundwater. In literature concerning microbiological iron conversions, X-ray diffraction (XRD) is a commonly used method for the phase identification of crystalline solids.

In literature concerning microbi-ological iron conversions, X-ray diffraction (XRD) is a commonly used method for the phase identi fication of crystalline solids.

XRD data of iron oxide magnetic nanoparticles are in agreement with the standard value of Fe 3 O 4 (JCPDS file no: 65- 3107). XRD analysis of the particles (Figure 2) shows well defined Bragg...

2015年1月1日 · The XRD results demonstrate the formation of pure iron and a mixed of iron oxides nanoparticles in acetone and deionized water respectively. For colloidal nanoparticles in acetone the UV-visible spectrum exhibited the characteristic optical extinction of iron nanoparticle.

2018年2月15日 · X-ray diffraction (XRD) is a commonly used technology to identify crystalline phases. However, care must be taken with the combination of XRD configuration and sample.

Characteristic properties of the material (morphology, structure, particle size distribution) were investigated by X-Ray diffraction (XRD), scanning electron microscopy and dynamic light scattering methods. Keywords. Zerovalent iron nanoparticle, synthesis, hydrogen reduction. 1. INTRODUCTION.

2019年7月23日 · Powder X-ray diffraction (XRD) is a common characterization technique for nanoscale materials. Analysis of a sample by powder XRD provides important information that is complementary to various microscopic and spectroscopic methods, such as phase identification, sample purity, crystallite size, and, in some cases, morphology.

2019年10月30日 · X-ray diffractometry (XRD) was used for the determination of major and minor chemical phases in the ores, k0-instrumental neutron activation analysis (k0-INAA) and inductively coupled plasma optical emission spectrometry (ICP-OES) were employed for the determination of elemental profiles of iron ores.

2022年1月1日 · Powder X-ray diffraction (XRD) is increasingly being used for the characterization of iron ore, sinter, and pellets thanks to the continuing developments in its instrumentation and software that enabled scientists and engineers to quickly analyze and quantify minerals and phases in often nonhomogeneous materials.
