Nanoparticles and interfaces with toxic elements in fluvial suspended sediment
(Universidad de la Costa, 2021)
Studies examining nanoparticles (NPs) and hazardous elements (HEs) contained in suspended sediments (SSs) are vital for watershed administration and ecological impact evaluation. The biochemical consequence of titanium-n ...
Implementation of a multilayer statistical physics model to interpret the adsorption of food dyes on a chitosan film
(Corporación Universidad de la Costa, 2021)
This paper reports the application of an advanced multilayer model to study the adsorption of food dyes FD&C blue No. 2, acid red 18, FD&C red No. 2, and FD&C yellow 5 from aqueous solutions with a chitosan film. These ...
Titanium nanoparticles in sedimented dust aggregates from urban children’s parks around coal ashes wastes
(Corporación Universidad de la Costa, 2021)
Recently, an increased interest in nanoscience applications can be observed in various fields. Soils around coal power plants may contain potentially hazardous elements (PHEs) and nanoparticles (NPs), which can be neo-produced ...
Deposition of nanoparticles on school eyeglasses in urban and rural areas: a methodology for a more real assessment of the possible impacts
(Corporación Universidad de la Costa, 2022)
Because incomplete confirmation is available concerning the influential role of atmosphere contamination on conjunctivitis, myopia, asthma, and allergic rhinitis in Brazil, the focus of the present work is to explore the ...
An analysis of nanoparticles derived from coal fly ash incorporated into concrete
(MDPI, 2022-03-26)
The environmental benefits of incorporating coal fly ash (CFA) into the concrete manufacturing process as a partial substitute for Portland cement are well known. What is less studied is the potential release of CFA derived ...
Green β-cyclodextrin nanosponges for the efficient adsorption of light rare earth elements: cerium and lanthanum
(Elsevier, 2023-06-15)
During the past decades, the removal and recovery of Lanthanum (La) and cerium (Ce) have attracted considerable interest owing to their importance in several industrial processes. In the present work, green nanosponge ...
An overview of forest residues as promising low-cost adsorbents
(Gondwana Research, 2021-06-26)
Anthropogenic activities have severely affected biogeochemical cycles on a global scale, resulting in a drastic increase in environmental problems, intensified by wastewater generation containing high levels of pollutants. ...
Adsorptive properties of highly porous activated carbon from açaí (Euterpe oleracea) towards the toxic herbicide atrazine
(Elsevier BV, 2023)
The great variety and possibilities of consumption of açaí pulp (Euterpe oleracea) have made its consumption increase considerably in recent years, mainly in Brazilian territory. The big problem is the generation of tons ...
Nanoparticles as vectors of other contaminants in estuarine suspended sediments: natural and real conditions
(Corporación Universidad de la Costa, 2021)
Studding the behaviour and danger of nanoparticles (NPs, minerals and amorphous phases) in the estuarine ecosystem is presently incomplete by the lack of measureable description of NPs in the ecological conditions, such ...
Polishing of painting process effluents through adsorption with biochar from winemaking residues
(Springer Science + Business Media, 2022-05-02)
A real industrial efuent from the pre-treatment and painting processes was polished through adsorption using alternative
biochar derived from grape pomace wastes. The biochar was produced in a pilot-scale plant from ...
