Adsorption of 2, 4-dichlorophenoxyacetic acid onto date seeds activated carbon: Equilibrium, kinetic and thermodynamic studies
(2012 , Article)
Adsorption isotherm and kinetics of 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide on activated carbon prepared from Barhi date seeds were determined from batch tests. The effects of contact time, initial herbicide ...
Batch study for herbicide bentazon adsorption onto palm oil fronds activated carbon
(2012 , Article)
The adsorption of herbicide bentazon from aqueous solution onto activated carbon derived from palm oil fronds (PFAC) was investigated through batch study. The effects of both; initial concentration of the bentazon (ranging ...
Use of lignite as a low-cost material for cadmium and copper removal from aqueous solutions: Assessment of adsorption characteristics and exploration of involved mechanisms
(
MDPI
, 2021 , Article)
Lignite, as an available and low-cost material, was tested for cadmium (Cd) and copper (Cu) removal from aqueous solutions under various static experimental conditions. Experimental results showed that the removal efficiency ...
Green synthesized zinc oxide nanoparticles for removal of carbamazepine in water and soil systems
(
Elsevier
, 2024 , Article)
During the COVID-19 pandemic, there was a significant increase in pharmaceutical releases (4 %), which created a pressing global need for solutions. In this study, we explored the use of zinc oxide nanoparticles (GS-ZnONPs) ...
Crosslinked chitosan–montmorillonite composite and its magnetized counterpart for the removal of basic fuchsin from wastewater: Parametric optimization using Box-Behnken design
(
Elsevier
, 2024 , Article)
Treating wastewater polluted with organic dyestuffs is still a challenge. In that vein, facile synthesis of a structurally simple composite of chitosan with montmorillonite (CS-MMT) using glutaraldehyde as a crosslinker ...
Effect of gas templating of resorcinol-formaldehyde xerogels on characteristics and performances of subsequent activated carbons
(
Elsevier Ltd
, 2019 , Article)
Gas-templated resorcinol formaldehyde-activated carbon xerogels (GT-RF-ACXs) were prepared from resorcinol-formaldehyde xerogels that were templated by infusing different gases (e.g., nitrogen, oxygen, methane, ethylene, ...
Adsorption of organic pollutants by natural and modified clays: A comprehensive review
(
Elsevier B.V.
, 2019 , Article Review)
Adsorption process has been widely used for treatment of wastewaters due to its simplicity and lower costs as compared to other traditional technologies. Among the alternative sorbent materials, the use of abundantly ...
Single and multi-component adsorption of aromatic acids using an eco-friendly polyaniline-based biocomposite
(
Elsevier B.V.
, 2017 , Article)
The polyaniline coated with an agricultural waste (Argan nut shell) was prepared via in-situ chemical polymerization and used as an adsorbent material for removal of trimellitic (Tri), hemimellitic (Hemi) and pyromellitic ...
