Adsorption of 4-Nitrophenol onto Iron Oxide Bentonite Nanocomposite: Process Optimization, Kinetics, Isotherms and Mechanism
(
Springer Science and Business Media Deutschland GmbH
, 2022 , Article)
Despite its importance in chemical industry, 4-Nitrophenol (4-NP) is a persistent organic pollutant that has serious effects on the ecosystem. In the present study, Box–Behnken design in response surface methodology was ...
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 ...
CO2 sorption kinetics of scaled-up polyethylenimine-functionalized mesoporous silica sorbent
(
American Chemical Society
, 2015 , Article)
Two CO2 solid sorbents based on polyethylenimine, PEI (Mn ∼ 423 and 10K), impregnated into mesoporous silica (MPS) foam prepared in kilogram quantities via a scale-up process were synthesized and systematically characterized ...
Synthesis of nanostructured novel ion-imprinted polymer for selective removal of Cu2+ and Sr2+ ions from reverse osmosis concentrated brine
(
Elsevier
, 2023 , Article)
This study aims to prepare an ion-imprinted polymer (IIP) using copper sulfate as a template and potassium persulfate as an initiator to selectively adsorb copper ions (Cu2+) from aqueous solutions and in an attempt to ...
Fluid-rock interactions in tight gas reservoirs: Wettability, pore structural alteration, and associated multiphysics transport
(
Elsevier
, 2023 , Book chapter)
Tight and unconventional reservoirs such as shales are rich in clay minerals that give rise to several fluid-rock interactions. The effect of such fluid-rock interactions is manifested at multiscales. The fluid-rock ...
The recovery of strontium ions from seawater reverse osmosis brine using novel composite materials of ferrocyanides modified roasted date pits
(
Elsevier
, 2023 , Article)
In this study, three types of adsorbents were used to remove and recover strontium ions (Sr2+) from aqueous and brine solution of seawater reverse osmosis (SWRO), namely roasted date pits (RDP) and RDP modified using copper ...
Iron Sulfide Scale Inhibition in Carbonate Reservoirs
(
American Chemical Society
, 2022 , Article)
Hydrocarbon production operations include water injection, varying stimulation approaches, and enhanced oil recovery techniques. These treatments often affect reservoir formation, production, and injection facilities. Such ...
Decoration of polylactic acid on graphene oxide for efficient adsorption of methylene blue and tetracycline
(
Elsevier Ltd
, 2023 , Article)
Decorating nanomaterials on graphene oxide (GO) can enhance its adsorption capacity and removal efficiency of water pollutants. In this study, for the first time, nano-sized polylactic acid (PLA) has been successfully ...
The emergence of multifunctional adsorbents and their role in environmental remediation
(
Elsevier Ltd
, 2021 , Article)
Water pollution is a growing issue which requires various treatment technologies for efficient and effective remediation. Adsorption is one of the dominant wastewater treatment technologies due to its flexible operation ...
Adsorption of Congo Red Dye Using Activated Carbon-Fe3O4 Composite
(
Qatar University Press
, 2023 , Conference Paper)
Activated Carbon-Fe3O4 composites were synthesized using co-precipitation method and used in batch experiments to adsorb Congo red dyes. The effect of adsorbent dosage, temperature and initial dye concentration was ...
