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 ...
Application of Beauveria bassiana spore waste as adsorbent to uptake acid red 97 dye from aqueous médium
(Universidad de la Costa, 2019-11-19)
The adsorption of acid red 97 dye (RED 97) by the waste of the filamentous fungus Beauveria bassiana was analyzed. The adsorbent was obtained as a waste of a fermentative process, and characterized by scanning electron ...
Functionalization of corn stover with 3-aminopropyltrietoxysilane to uptake Reactive Red 141 from aqueous solutions
(Universidad de la Costa, 2019-09-07)
An alternative and low-cost adsorbent (CS–APTES) was developed by the functionalization corn stover (CS) with 3-aminopropyltrietoxysilane (APTES) using a simple method. Several analytical techniques were used to prove the ...
Woody residues of the grape production chain as an alternative precursor of high porous activated carbon with remarkable performance for naproxen uptake from water
(Springer Science + Business Media, 2021-10-16)
Activated carbon prepared from grape branches was used as a remarkable adsorbent to uptake naproxen and treat a synthetic mixture from aqueous solutions. The material presented a highly porous texture, a surface area of ...
Adsorption performance of food red 17 dye using an eco-friendly material based on luffa cylindrica and chitosan
(Elsevier, 2021-11-22)
Luffa cylindrica (LC), a lignocellulosic material coveted for its versatility, was investigated to immobilize crosslinked chitosan and remove Food red 17 (FR17) dye from aqueous solutions. LC/chitosan was crosslinked with ...
Treatment of effluents containing 2- chlorophenol by adsorption onto chemically and physically activated biochars
(Corporación Universidad de la Costa, 2020)
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 ...
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 ...
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 ...
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 ...
