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 ...
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 ...
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, ...
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 ...
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 ...
Polishing of painting process effluents through adsorption with biochar from winemaking residues
(Springer Science + Business Media, 2022-05-02)
A real industrial efuent from the pre-treatment and painting processes was polished through adsorption using alternative
biochar derived from grape pomace wastes. The biochar was produced in a pilot-scale plant from ...
Effective adsorptive removal of atrazine herbicide in river waters by a novel hydrochar derived from Prunus serrulata bark
(Springer Science + Business Media, 2021)
In this work, a novel and effective hydrochar was prepared by hydrothermal treatment of Prunus serrulata bark to remove the pesticide atrazine in river waters. The hydrothermal treatment has generated hydrochar with a rough ...
Effective removal of non-steroidal anti-inflammatory drug from wastewater by adsorption process using acid-treated Fagopyrum esculentum husk
(Springer Science + Business Media, 2022)
In this work, buckwheat husks (Fagopyrum esculentum) were modified by acid treatment and posteriorly employed to remove the ketoprofen in batch adsorption. The characterization results indicated that a more irregular surface ...
Cyanobacterial biomass as a potential biosorbent for the removal of recalcitrant dyes from water
(MDPI Multidisciplinary Digital Publishing Institute, 2021-11-10)
The accumulation of cyanobacteria produced due to eutrophication processes and the increment of different pollutants in water as a result of industrial processes affects aquatic environments such as the ocean, rivers, and ...
Optimization of ketoprofen adsorption from aqueous solutions and simulated effluents using H2SO4 activated Campomanesia guazumifolia bark
(Springer Science + Business Media, 2021)
This study used the bark of the forest species Campomanesia guazumifolia modified with H2SO4 to absorb the anti-inflammatory ketoprofen from aqueous solutions. FTIR spectra confirmed that the main bands remained after the ...
