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 ...
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 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 ...
Understanding the Cu2+ adsorption mechanism on activated carbon using advanced statistical physics modelling
(Springer Science + Business Media, 2022)
Adsorption modeling via statistical physics theory allows to understand the adsorption mechanism of heavy metal ions. Therefore, this paper reports the analysis of the mechanism of copper ion (Cu2+) adsorption on four ...
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, ...

Synthesis and application of ferromagnetic graphene oxide nanocomposite as an effective adsorbent for Clonazepam: Batch experiments, modeling, regeneration, and phytotoxicity
(Elsevier BV, 2022)
In this work, a ferromagnetic graphene oxide nanocomposite (mGO) was produced, characterized, and tested for clonazepam removal from water. After the nanocomposite production and characterization, adsorption tests showed ...
KOH activated carbons from Brazil nut shell: preparation, characterization, and their application in phenol adsorption
(Institution of Chemical Engineers, 2022-11)
Activated carbons named AC105 and AC11 were prepared from Brazil nut shells using the weight ratios of Brazil nut shells: KOH of 1:0.5 and 1:1, respectively. The prepared materials were characterized using different ...
Improved adsorption of the toxic herbicide diuron using activated carbon obtained from residual cassava biomass (manihot esculenta)
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-11-04)
The production and consumption of cassava (Manihot esculenta) occur in several places worldwide, producing large volumes of waste, mostly in the form of bark. This study sought to bring a new purpose to this biomass through ...
Transformation of residual açai fruit (Euterpe oleracea) seeds into porous adsorbent for efficient removal of 2,4-dichlorophenoxyacetic acid herbicide from waters
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-11-11)
Brazil’s production and consumption of açai pulp (Euterpe oleracea) occur on a large scale. Most of the fruit is formed by the pit, which generates countless tons of residual biomass. A new purpose for this biomass, making ...
