Comparative removal of emerging contaminants from aqueous solution by adsorption on an activated carbon
(Taylor & Francis, 2019)
info:eu-repo/semantics/article,
Batch sorption experiments were performed to study the adsorption of six emerging pollutants from aqueous solutions using a commercial granular activated carbon as adsorbent. Caffeine, clofibric acid, diclofenac, gallic ...
Zeolite synthesis from industrial wastes
(Elsevier, 2019)
info:eu-repo/semantics/article,
Conventional synthesis conditions for each type of zeolite are tabulated and reported by the International Zeolite Association Structure Commission (IZA) and most of them are synthesized from commercial reagents, but they ...
Improvement of the adsorption properties of an activated carbon coated by titanium dioxide for the removal of emerging contaminants
(Elsevier, 2019)
info:eu-repo/semantics/article,
Three activated carbon coated titanium dioxide composites are evaluated as adsorbents for the removal of three pharmaceutical compounds: clofibric, gallic and salicylic acids from aqueous solutions. These composite materials ...
Modification of the Thomas model for predicting unsymmetrical breakthrough curves using an adaptive neural-based fuzzy inference system
(IWA Publishing, 2019)
info:eu-repo/semantics/article,
The Thomas equation is a popular model that has been widely used to predict breakthrough curves (BTCs) when describing the dynamic adsorption of different pollutants in a fixed-bed column system. However, BTCs commonly ...
White and red Brazilian Sao Simao's kaolinite-TiO2 nanocomposites as catalysts for toluene photodegradation from aqueous solutions
(MDPI, 2019)
info:eu-repo/semantics/article,
The presence of volatile organic compounds in groundwater is a major concern when it is used as a drinking water source because many of these compounds can adversely affect human health. This work reports on the preparation ...
Separación electrostática de una emulsión de glicerina en biodiésel con aplicación de varios voltajes y distancias entre electrodos
(Centro de Información Tecnológica, 2019)
info:eu-repo/semantics/article,
Con el propósito de aplicar una tecnología limpia y de bajo consumo energético en la separación de emulsiones, se construyó un separador electrostático de 1,0 dm3. Se utilizaron electrodos de cobre rectangulares. Para los ...
Effect of high pressure on the reducibility and dispersion of the active phase of Fischer-Tropsch catalysts
(MDPI, 2019)
info:eu-repo/semantics/article,
The effect of high pressure on the reducibility and dispersion of oxides of Co and Fe supported on -Al2O3, SiO2, and TiO2 has been studied. The catalysts, having a nominal metal content of 10 wt.%, were prepared by incipient ...
A layered titanosilicate AM-4 as a novel catalyst for the synthesis of 1-methoxy-2-propanole from propylene oxide and methanol
(Elsevier, 2019)
info:eu-repo/semantics/article,
In this paper we report for the first time the catalytic properties of the titanosilicate AM-4 in the synthesis of 1-methoxy-2-propanol (PGME) from methanol and propylene oxide (PO). PGME is widely used as a pollution-free ...
Adsorption recovery of Ag(I) and Au(III) from an electronics industry wastewater on a clay mineral composite
(University of Science and Technology BeijingSpringer, 2019)
info:eu-repo/semantics/article,
The aim of this work is to investigate the ability of an adsorbent of a clay mineral composite to remove and recover gold and silver ions from wastewater. The composite was prepared by mixing phosphogypsum (PG), obtained ...
