Adsorption and desorption equilibria of nitrogen, methane, ethane, and ethylene on date-pit activated carbon
( American Chemical Society , 2010 , Article)Date pits were used to produce a highly porous activated carbon. The resulting date-pit activated carbon was used in a volumetric adsorption apparatus to measure the vapor-phase adsorption and desorption of nitrogen, ... -
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 ... -
Box-Behnken approach for optimization of Cr(III) removal from a real tanning effluent using powdered marble
( Springer Science and Business Media Deutschland GmbH , 2022 , Article)During the tanning step, 30-40% of trivalent chromium remains in the solid and liquid wastes, generating highly polluted sewage. In this study, powdered marble was used as a low-cost adsorbent to remove trivalent chromium ... -
Carbon dioxide (CO2) capture: Absorption-desorption capabilities of 2-amino-2-methyl-1-propanol (AMP), piperazine (PZ) and monoethanolamine (MEA) tri-solvent blends
( Elsevier B.V. , 2016 , Article)In this study, highly concentrated tri-solvent blends containing 2-amino-2-methyl-1-propanol (AMP), piperazine (PZ) and monoethanolamine (MEA) were experimentally investigated for their potential capabilities in carbon ... -
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 ... -
Desorption of chloramphenicol from ordered mesoporous carbon-alginate beads: Effects of operating parameters, and isotherm, kinetics, and regeneration studies
( Elsevier Ltd , 2021 , Article)This study has investigated the desorption of an emerging contaminant, known as chloramphenicol (CPC), from ordered mesoporous carbon (OMC)-alginate beads. The effects of initial concentration, operating temperature, and ... -
Effect of CO2 content on the natural gas production from tight gas sandstone reservoirs
( Society of Petroleum Engineers (SPE) , 2017 , Conference Paper)The simulation of the gas flow in tight sandstone reservoir is a very complicated process. Several mechanisms contributed to the natural gas production in tight sandstone reservoirs. One of the main mechanisms is the gas ... -
Kinetics of CO2 Adsorption/Desorption of Polyethyleneimine-Mesoporous Silica
( Wiley-VCH Verlag , 2017 , Article)The kinetics of adsorption of CO2 on solid sorbents based on polyethyleneimine/mesoporous silica (PEI/MPS) was studied by following the mass gain during CO2 flow. Linear (PEI-423) and branched (PEI-10k) polymers were ... -
Macroalgae as an eco-friendly and successful green technology for the removal of crystal violet from synthetic and real wastewater
( Elsevier B.V. , 2023 , Article)Crystal violet (CV) is one of the water pollutants that can cause potential harm to living beings and the environment. Different methods are applied for the removal of CV from wastewater, however, a cheap and environmentally ... -
Removal of copper ions from aqueous solution using NaOH-treated rice husk
( Springer Nature , 2020 , Article)The present study investigates the removal of copper ions (Cu (II)) from aqueous solution using chemically treated rice husk (TRH). The chemical treatment was carried out using NaOH solution and the effect of contact time ... -
Valorization of salt post-modified poultry manure biochars for phosphorus recovery from aqueous solutions: investigations on adsorption properties and involved mechanism
( Springer , 2021 , Article)In this research work, raw poultry manure biochar (RPM-B) was post-modified by two metal salts and then evaluated for P recovery from aqueous solutions in batch mode. The modified biochar characterization showed that RPM-B ...
