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 ...
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 ...
Treatment of residual lubricating oil using rice husk-based material as ecological adsorbent
(Springer Japan, 2023)
One of the most significant environmental problems the world population faces is the inadequate disposal of petroleum derivatives. Lubricant oil is a hazardous waste due to its properties and characteristics. This study ...
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 ...
Conversion of foliar residues of Sansevieria trifasciata into adsorbents: dye adsorption in continuous and discontinuous systems
(Springer Science + Business Media, 2022-09-04)
The study analyzed the potential of leaf powder prepared from the residual leaves of the species Sansevieria trifasciata, as a potential adsorbent for methylene blue (MB) removal. The equilibrium was reached fast for almost ...
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, ...
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. ...
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 ...
An overview of geological originated materials as a trend for adsorption in wastewater treatment
(2021-01-30)
Adsorption is a unit operation widely used for the tertiary treatment of the most diverse effluents, whose mechanism is based on removing recalcitrant compounds from the organic and inorganic origin. In this process, ...
Treatment of effluents containing 2-chlorophenol by adsorption onto chemically and physically activated biochars
(Corporación Universidad de la Costa, 2020-09-09)
The application of adsorption using biochars for the remediation of effluents containing emerging contaminants, including chlorophenols, is a hotspot and trend development in the literature. This treatment is more interesting ...
