متن کاملArsenic Adsorption on Lanthanum-Impregnated Activated Alumina: Spectroscopic and DFT Study.
Rare earth-modified adsorbents (REMAs) have been widely used to remove oxyanion pollutants from water, including arsenic (As). However, the molecular-level structural information and reactions at the liquid/solid interface are still murky, which limits the design of applicable REMAs. Herein, a lanthanum-impregnated activated alumina (LAA) was synthesized as a representative REMA, and its As upt...
متن کاملAdsorption of sodium hexanoate on α-alumina.
Neutron reflection and adsorption isotherm measurements have been used to study the adsorption behaviour of hexanoic acid onto α-alumina surfaces. Importantly, the pH dependence of the behaviour has been characterised with a pronounced maximum in adsorption identified at a pH of approximately 5, close to the pKa of the acid. The adsorbed layer is identified as a bilayer, which is reasonable giv...
متن کاملAdsorption of Hydrogen Fluoride on Alumina
In the smelting of aluminium, HF fumes are produced that are subsequently trapped by absorption onto alumina. The factors that affect the adsorption capacity of alumina have been studied previously and are weU established, but the mechanism by which HF adsorbs onto the alumina surface is not well understood. In this study, x-ray photoelectron spectroscopy (XPS) was used to investigate the natur...
متن کاملVibrational spectroscopic studies on CO adsorption, NO adsorption CO þ NO reaction on Pd model catalysts
CO adsorption, NO adsorption and CO þ NO reaction on various Pd model catalysts have been studied using vibrational spectroscopy from ultrahigh vacuum (UHV) up to elevated pressures (B1 bar) and the kinetics of the reaction compared with the conventional high surface area Pd/g-Al2O3 catalysts. The structure sensitivity of the CO þ NO reaction on different Pd surfaces is explained using Pd(111),...
