This paper describes the synthesis of paramegnetic iron-containing hydroxyapatite nanoparticles and their increased Cu(2+) sorbent capacity when using Ca(2+) complexes soluble bioorganic substrates from urban wastes as precursors. A thorough characterization particles by TEM, XRD, FTIR spectroscopy, specific surface area, TGA, XPS, DLS indicates that loss crystallinity, a higher an oxygen content, formation iron phases strongly enhance adsorption hydroxyapatite-based materials. However,...
The capability of paramegnetic iron-containing hydroxyapatite (Fe-nAp) and waste bioorganic subtrates templeted (SBO-Fe-nAp) nanoparticles, as Pb(II) cations adsorbants were investigated compared to those synthetic (nAp).Surface bulk characterization techniques XPS, XRD, electrophoretic mobility, FTIR spectroscopy, DLS, TEM used investigate the adsorption mechanisms involved ICP-AES determine concentrations in aqueous solutions.The apatite-based nanoparticles found be efficient materials for...
A wet-synthetic method is described to obtain magnetic, air-stable, zero-valent iron nanoparticles coated with an alkanedioic acid.The particles can be immobilized in amino-substituted polysiloxane matrix provide materials capable of dechlorinating, debrominating, and deiodinating a wide variety halogenated organic molecules dissolved initially highly polar medium.The methodology involves diffusion the into matrix, their reaction embedded nanoparticles, then dehalogenated products back...
There has been a growing interest in applying nanoparticles for enhanced oil recovery. Within this context, there is need to understand the influence of factors involved formulation nanoparticle based emulsions over their properties. In contribution, functionalized SiO2 two different sizes were synthesized and used as surfactants with model oils: squalane vacuum gas oil. Factorial experiments made analyze effects particle size, water content, emulsification energy, non-additive (second third...
Janus nanoparticles have applications in many fields. Particularly, the oil industry is interested applying them for enhanced recovery. Within this context, there a need to understand influence of factors involved formulation crude type emulsions over their properties and rheological behavior. In contribution, spherical SiO 2 two different sizes were synthesized used as surfactants aqueous with model oils: namely, squalane vacuum gas oil. Factorial experiments designed made analyze effects...
