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 ...
Enhancement of the adsorption of hexacyanoferrate (III) ion on granular activated carbon by the addition of cations: a promissory application to mining wastewater treatment
(Corporación Universidad de la Costa, 2020-07-27)
The influence of the addition of cations on the adsorption of [Fe(CN)6] 3− on granular activated carbon (GAC) was evaluated. The tests were performed at three pH values (3, 8.2, and 13) to determine the repulsion or ...
Adsorption of ibuprofen, ketoprofen, and paracetamol onto activated carbon prepared from effluent treatment plant sludge of the beverage industry
(Corporación Universidad de la Costa, 2020-09-15)
The presence of emerging contaminants such as pharmaceuticals in aquatic means presents as a serious threat, since their real consequences for the environment and human health are not well known. Therefore, this work ...
Composite carbon materials from winery composted waste for the treatment of effluents contaminated with ketoprofen and 2-nitrophenol
(Corporación Universidad de la Costa, 2021)
The present work consisted of preparing and characterizing composite carbon materials (WRCC) from raw winery residues (WR) activated with zinc chloride to produce a carbon adsorbent. The WRCC was used for the adsorption ...
Evaluation of Ocotea puberula bark powder (OPBP) as an effective adsorbent to uptake crystal violet from colored effluents: alternative kinetic approaches
(Universidad de la Costa, 2020-04-30)
The Ocotea puberula bark powder (OPBP) was evaluated as an effective adsorbent for the removal of crystal violet (CV) from colored effluents. OPBP was characterized and presented a surface with large cavities, organized ...
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 ...
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 ...
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 ...
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 ...
