Euterpe oleracea-based biochar for clonazepam adsorption: synthesis, characterization, adsorption properties, and toxicity assays
(Springer Science + Business Media, 2023-02-25)
The consumption of açaí fruit (Euterpe oleracea) has largely increased worldwide, resulting in a significant increase in the demand for its pulp. As a result, the small producing communities end up with large amounts of ...
Efficient removal of naproxen from aqueous solution by highly porous activated carbon produced from Grapetree (Plinia cauliflora) fruit peles
(Corporación Universidad de la Costa, 2021)
In this work, jabuticaba (Plinia cauliflora) fruit peels were pyrolyzed in the presence of zinc chloride to generate a novel porous adsorbent to remove naproxen (NPX) from aqueous solutions. The maximum adsorption capacity ...
Nanominerals assemblages and hazardous elements assessment in phosphogypsum from an abandoned phosphate fertilizer industry
(Universidad de la Costa, 2020)
The present work investigates hazardous elements and nanomineralogical assemblages of phosphogypsum waste from an abandoned phosphate fertilizer industry located in Santa Catarina state (Brazil). Correlations between the ...
Volcanic rock powder residues as precursors for the synthesis of adsorbents and potential application in the removal of dyes and metals from water
(Elsevier BV, 2021-11-30)
The present study verified the potential of volcanic rock powder residues originating from the extraction of semi-precious rocks in the state of Rio Grande do Sul, Brazil, as precursors or adsorbents for dyes and metallic ...
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 ...
Transforming shrub waste into a high-efficiency adsorbent: Application of Physalis peruvian chalice treated with strong acid to remove the 2,4-dichlorophenoxyacetic acid herbicide
(Corporación Universidad de la Costa, 2021)
In this study, the chalice generated from the production of the Physalis peruviana fruit was subjected to a treatment with sulfuric acid and applied in the adsorption of 2,4-Dichlorophenoxyacetic acid (2,4-D). The precursor, ...
Cassava bagasse as an alternative biosorbent to uptake methylene blue environmental pollutant from water
(Springer Science + Business Media, 2023-02-23)
Herein, the methylene blue (MB) biosorption from the agroindustrial residue (cassava bagasse) is reported. The cassava bagasse residue presented an irregular surface, anionic character, and low specific surface area. The ...
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. ...
Simultaneous production of mesoporous biochar and palmitic acid by pyrolysis of brewing industry wastes
(Universidad de la Costa, 2020)
Pyrolysis of malt bagasse was carried out to obtain simultaneously a mesoporous biochar and an oil fraction rich in palmitic acid. The best result for biochar production was at 500 °C with holding time of 10 min. The yields ...
