Pore volume and surface diffusion model (PVSDM) applied for single and binary dye adsorption systems
(Institution of Chemical Engineers, 2022)
The PVSDM model was used for single and binary dye adsorption systems. This model is commonly used for adsorption in single systems, but this is the first time used in a binary mixture of dyes in the literature. To that ...
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 ...
Application of araçá fruit husks (Psidium cattleianum) in the preparation of activated carbon with FeCl3 for atrazine herbicide adsorption
(Institution of Chemical Engineers, 2022-04)
The residual husks of the edible fruits of Psidium cattleianum were carbonized with FeCl3 as an activating agent and used as an adsorbent to remove the toxic herbicide. After the carbonization step, changes in the material’s ...
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 ...
Effective removal of non-steroidal anti-inflammatory drug from wastewater by adsorption process using acid-treated Fagopyrum esculentum husk
(Springer Science + Business Media, 2022)
In this work, buckwheat husks (Fagopyrum esculentum) were modified by acid treatment and posteriorly employed to remove the ketoprofen in batch adsorption. The characterization results indicated that a more irregular surface ...
Understanding the Cu2+ adsorption mechanism on activated carbon using advanced statistical physics modelling
(Springer Science + Business Media, 2022)
Adsorption modeling via statistical physics theory allows to understand the adsorption mechanism of heavy metal ions. Therefore, this paper reports the analysis of the mechanism of copper ion (Cu2+) adsorption on four ...
Investigation of biochar from Cedrella fissilis applied to the adsorption of atrazine herbicide from an aqueous medium
(Elsevier BV, 2022)
Biochar was produced from the sawdust of the wood forest species Cedrella fissilis and later used as an adsorbent to remove atrazine herbicide from aqueous media. Biochar showed high thermal stability, an amorphous structure, ...
Effects of atmospheric pollutants on human health and deterioration of medieval historical architecture (North Africa, Tunisia)
(Elsevier BV, 2022-01)
Air pollution is a factor of concern on a global scale, accelerating the deterioration of historic medieval architecture and having harmful effects on human health. The general objective of this study is to understand the ...
