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 ...
Adsorption of atrazine herbicide from water by diospyros kaki fruit waste activated carbon
(Elsevier, 2021-11-10)
In this work, Diospyros kaki fruit waste was employed as a precursor material to develop a high surface area activated carbon, which efficiently removed the toxic herbicide atrazine (ATZ) from synthetic water solutions and ...
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, ...
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 ...
One step acid modification of the residual bark from Campomanesia guazumifolia using H2SO4 and application in the removal of 2,4-dichlorophenoxyacetic from aqueous solution
(Taylor and Francis Ltd., 2021)
The residual bark of the tree species Campomanesia guazumifolia was successfully modified with H2SO4 and applied to remove the toxic herbicide 2.4-dichlorophenoxyacetic (2.4-D) from aqueous solutions. The characterization ...
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 ...
An overview of geological originated materials as a trend for adsorption in wastewater treatment
(2021-01-30)
Adsorption is a unit operation widely used for the tertiary treatment of the most diverse effluents, whose mechanism is based on removing recalcitrant compounds from the organic and inorganic origin. In this process, ...
An overview of forest residues as promising low-cost adsorbents
(Gondwana Research, 2021-06-26)
Anthropogenic activities have severely affected biogeochemical cycles on a global scale, resulting in a drastic increase in environmental problems, intensified by wastewater generation containing high levels of pollutants. ...
Conversion of foliar residues of Sansevieria trifasciata into adsorbents: dye adsorption in continuous and discontinuous systems
(Springer Science + Business Media, 2022-09-04)
The study analyzed the potential of leaf powder prepared from the residual leaves of the species Sansevieria trifasciata, as a potential adsorbent for methylene blue (MB) removal. The equilibrium was reached fast for almost ...
Treatment of residual lubricating oil using rice husk-based material as ecological adsorbent
(Springer Japan, 2023)
One of the most significant environmental problems the world population faces is the inadequate disposal of petroleum derivatives. Lubricant oil is a hazardous waste due to its properties and characteristics. This study ...
