High-performance removal of 2,4-dichlorophenoxyacetic acid herbicide in water using activated carbon derived from Queen palm fruit endocarp (Syagrus romanzoffiana)
(Corporación Universidad de la Costa, 2021-02)
In this work, an activated carbon sample with a high adsorptive performance for the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) was prepared from queen palm endocarp (Syagrus romanzoffiana) by pyrolysis process. The ...
Application of biowaste generated by the production chain of pitaya fruit (Hylocereus undatus) as an efficient adsorbent for removal of naproxen in water
(Springer Science + Business Media, 2022-02-02)
Pharmaceutical compounds are a serious problem in the environment. They cause damage to the aquatic, animal, and human organisms and soon became considered emerging pollutants where their removal is extremely urgent. Among ...
Evaluation of electrolytic reactor configuration for the regeneration of granular activated carbon saturated with methylene blue
(Corporación Universidad de la Costa, 2020-05-27)
The performance of an electrochemical process for the regeneration of granular activated carbon (GAC) was
evaluated using boron-doped diamond (BDD) anodes. Three different configurations were tested in the reactor:
fluidized ...
Development of a biosponge based on Luffa cylindrica and crosslinked chitosan for Allura red AC adsorption
(Corporación Universidad de la Costa, 2021)
A new bioadsorbent from Luffa cylindrica and cross-linked chitosan was proposed in the present study. Luffa was used as a natural support medium for chitosan crosslinked with glutaraldehyde (LCsG) and epichlorohydrin (LCsE). ...
Synthesis of geopolymers from fly and bottom ashes of a thermoelectrical power plant for metallic ions adsorption
(Springer Science + Business Media, 2021)
A series of geopolymers were synthesized from fly and bottom ashes of a thermoelectrical power plant located in the Brazilian southern, aiming to add value for these wastes. The geopolymers were prepared in conventional ...
Selective adsorption of gadolinium from real leachate using a natural bentonite clay
(Elsevier BV, 2023)
This article investigated the recovery of Gd3+ from real leachate of phosphogypsum (PG) using natural bentonite clay. Firstly, a detailed adsorption study was performed using synthetic Gd3+ solutions. Then, it was investigated ...
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, ...
Efficient uptake of angiotensin-converting enzyme ii inhibitor employing graphene oxide-based magnetic nanoadsorbents
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-01-10)
This paper reports a high efficiency uptake of captopril (CPT), employing magnetic graphene oxide (MGO) as the adsorbent. The graphene oxide (GO) was produced through an oxidation and exfoliation method, and the magnetization ...
Critical rare earth metal adsorption onto expanded vermiculite: accurate modeling through response surface methodology and machine learning techniques
(Elsevier BV, 2023)
The circular economy of rare earth metals (REM), such as dysprosium, is essential for a sustainable future in clean energy and high-tech fields. Adsorption has gained attention to recover and reintegrate REM into the ...
Green synthesis of carbon nanotubes impregnated with metallic nanoparticles: Characterization and application in glyphosate adsorption
(2021)
In the present work, multi-walled carbon nanotubes (MWCNTs) were used as support material for the impregnation of metallic nanoparticles (MNPs) produced by green synthesis. The influences of the plant extracts (pomegranate ...
