(Elsevier B.V., 2018)This research describes the development of a very cheap mesoporous silica material similar to hexagonal mesoporous silica (HMS) and using a silicate extract as precursor. This precursor is obtained from cheap fly ash by ...
-
(Royal Soc Chemistry, England, 2021)The transient combustion of biomass leads to the evolution of a variety of pollutants (NO, CO, organic compounds, and many others) that can react with each other on a suitable catalyst to generate compounds of lower ...
-
(2003)The presence of soluble heavy metals in wastewaters, can be toxic for the living beings depending on theirs concentrations. Several studies have been proposed in the literature about the use of natural and modified barks, ...
-
(Elsevier B.V., 2016)Adsorption of As (V) by poly (N-octyl-4-vinylpyridinium) bromide (P4VPyC8), used as solid phase, was studied. Determination of As (V) was carried out by direct measurement of the fluorescence intensity on the solid phase. ...
-
(Wiley, 2020)Acute Cr(VI)water pollution due to anthropogenic activities is an increasing worldwide concern. The high toxicity and mobility of Cr(VI)makes it necessary to develop dual adsorbent/ion-reductive materials that are able to ...
-
(Elsevier, 2018)Cu/Al and Cu/Cr layered double hydroxides (LDH) were synthesized using a simple co-precipitation method at room temperature. These particles were further modified by Co+2 incorporation, and calcined at 500 degrees C for ...
-
(Wiley-VCH Verlag, 2014)© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.The assessment of the environmental fate of glyphosate and its degradation product (aminomethylphosphonic acid) is of great interest given the widespread use of the herbicide. ...
-
(Springer Verlag, 2017)Biosolids contain inorganic and organic contaminants, including pharmaceutical and personal care products (PPCPs) that have accounted for a series of emerging contaminants, such as triclosan (TCS) and the hormone 17 ...
-
(MDPI, 2020)Adsorption technologies are a focus of interest for the removal of pollutants in water treatment systems. These removal methods offer several design, operation and efficiency advantages over other wastewater remediation ...
-
(MDPI, 2021)Water pollution by heavy metals has significant effects on aquatic ecosystems. Copper is one of the heavy metals that can cause environmental pollution and toxic effects in natural waters. This encourages the development ...
-
(Elsevier, 2018)In this work, we present the synthesis of Ag doped TiO2 materials. The products are characterized by powder X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, nitrogen adsorption, and ...
-
(2007)The interaction between adsorbates of different nature and plasmonic nanoparticles is reviewed here on the basis of the work done in our laboratory in the past few years. The paper is structured for analyzing the interaction ...
-
(2009)The adsorption behavior of polycations at ionic strengths (I) ranging from 0.001 to 0.1 onto silicon wafers was studied by means of ellipsometry, contact angle measurements and atomic force microscopy (AFM). Polycations ...
-
(MDPI, 2020)This article describes the use of beta-cyclodextrin-based carbonate nanosponges (NSs) decorated with superparamagnetic Fe3O4 nanoparticles to study and investigate the potential removal of dinotefuran (DTF) from wastewater. ...
-
(Sociedad Chilena de Química, 2010)The microencapsulation of the non-specific basic extractant trioctylamine in polymeric matrices synthesized from styrene and divinylbenzene was studied. The microcapsules were prepared by adding the amine compound during ...
-
(MDPI, 2021)The presence of hexavalent chromium water pollution is a growing global concern. Among the currently applied technologies to remove Cr-VI, its adsorption and photocatalytic reduction to Cr-III less mobile and toxic forms ...
-
(Hindawi, 2020)Protein adsorption is influenced by many factors such as temperature, pH, protein size and structure, or surface energy and roughness, among others. Self-assembled monolayers (SAMs) and the Langmuir-Blodgett (LB) technique ...
-
(Elsevier, 2020)A noble-metal free and surface defect-induced mesoporous mixed valent NiO decorated TiO2 heterostructure with tuned bandgap has been successfully prepared. Its outstanding visible-light driven hydrogen evolution and its ...
-
Recent advances in magnetic nanoparticles and nanocomposites for the remediation of water resources (MDPI, 2020)Water resources are of extreme importance for both human society and the environment. However, human activity has increasingly resulted in the contamination of these resources with a wide range of materials that can ...
-
(MDPI, 2021)Pollution due to acidic and metal-enriched waters affects the quality of surface and groundwater resources, limiting their uses for various purposes. Particularly, manganese pollution has attracted attention due to its ...
