The effects of solution pH and temperature on the adsorption fluoride onto bone char made from cattle bones were investigated in this work. It was found that maximum took place at 3 capacity decreased nearly 20 times augmenting to 12. This behavior attributed electrostatic interactions between surface ions solution. not influenced by range 15 35 °C. A comparison capacities among several adsorbents revealed 2.8 36 greater than those a commercial activated alumina (F-1) carbon (F-400). is...
Silver nanoparticles with a narrow size distribution were synthesized over the surface of two different commercial TiO(2) particles using simple aqueous reduction method. The reducing agent used was NaBH(4); molar ratios TiO(2):Ag also used. nanocomposites thus prepared characterized transmission electron microscopy (TEM), scanning (STEM), (SEM), energy-dispersive spectroscopy (EDS), x-ray photoelectron (XPS), diffraction (XRD), dynamic light scattering (DLS) and UV-visible (UV-vis)...
PM2.5 were collected in March 2006 during the MILAGRO campaign (Megacities Initiative: Local and Global Research Observations) carried out northern region of Mexico City Metropolitan Area (MCMA), order to realize an individual characterization particulate matter through scanning electron microscopy coupled with energy–dispersive X–Ray analyzer (SEM–EDX), acquiring information from around 6 000 particles about their morphology, size superficial chemical composition. Measurements aerosol...
Apical periodontitis is an inflammation leading to the injury and destruction of periradicular tissues. It a sequence events that starts from root canal infection, endodontic treatment, caries, or other dental interventions. Enterococcus faecalis ubiquitous oral pathogen challenging eradicate because biofilm formation during tooth infection. This study evaluated hydrolase (CEL) fungus Trichoderma reesei combined with amoxicillin/clavulanic acid as treatment against clinical E. strain....
The adsorption capacity of sepiolite towards the removal heavy metal ions from aqueous solution was studied in this work, with equilibrium data being obtained a bath adsorber. sample chemically stable over pH range 2–12, but dissolved acidic solutions values less than 2. Langmuir isotherm gave better fit experimental data, since average absolute percentage deviation lower that Freundlich isotherm. decreased following order: Cr(III) > Cd(II) Cu(II) Zn(II) Ni(II) Ag(I). Increasing...
Abstract Candelilla wax (CW) organogelation is a promising method for providing structure to solid‐like fat‐based foods, cosmetics, and drug delivery systems. The main component, n ‐hentriacontane (C31), defines, large extent, the thermal properties of CW. CW complex mixture ‐alkanes, fatty acids, triterpenic alcohols, alcohols. In this initial examination role components on phase behavior structure, binary mixtures C31 melissic acid (C30) were studied in bulk solutions vegetable oil. Binary...
Abstract The effects of surface properties and solution pH temperature on the adsorption cadmium(II) onto activated carbon fiber cloth (ACC) made from polyacrylonitrile (PAN) were investigated in this work. ACC was oxidized with HNO3 concentration acidic sites increased during oxidation whereas that basic ones diminished. capacity higher than without because contained greater sites. It found maximum took place at 8 near 22 times, augmenting 2 to 8. diminished average twofold, increasing 15...
