Pb(II) Uptake from Polluted Irrigation Water Using Anatase TiO Nanoadsorbent.

The adsorption characteristics of titanium dioxide nanoparticles (nano-TiO) for the removal of Pb(II) from irrigation water were investigated in this work. To accomplish this, several adsorption factors, such as contact time and pH, were tested to assess adsorption efficiencies and mechanisms. Before and after the adsorption experiments, commercial nano-TiO was studied using X-ray diffraction (XRD), scanning and transmission electron microscopy (SEM and TEM), energy dispersive spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS).

Strain and Grain Size Determination of CeO and TiO Nanoparticles: Comparing Integral Breadth Methods versus Rietveld, μ-Raman, and TEM.

Various crystallite size estimation methods were used to analyze X-ray diffractograms of spherical cerium dioxide and titanium dioxide anatase nanoparticles aiming to evaluate their reliability and limitations. The microstructural parameters were estimated from several integral breadth methods such as Scherrer, Monshi, Williamson-Hall, and their variants: (i) uniform deformation model, (ii) uniform strain deformation model, and (iii) uniform deformation energy density model. We also employed the size-strain plot and Halder-Wagner method.
