Investigation of the effect of polyelectrolyte structure and type on the electrokinetics and flocculation behavior of bentonite dispersions
(
Elsevier B.V.
, 2017 , Article)
The influence of surface charge type and density, and molecular weight of cationic, anionic and amphoteric polyacrylamide (PAM) on the electrokinetics, adsorption and flocculation behavior of highly stable bentonite ...
Energetic investigation of the adsorption process of CH4, C 2H6 and N2 on activated carbon: Numerical and statistical physics treatment
(
Elsevier
, 2014 , Article)
The adsorption energy distribution (AED) function of a commercial activated carbon (BDH-activated carbon) was investigated. For this purpose, the integral equation is derived by using a purely analytical statistical physics ...
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 ...
Brine management strategies, technologies, and recovery using adsorption processes
(
Elsevier B.V.
, 2021 , Article)
The world is experiencing serious shortages, unequal distributions, and contamination of the available freshwater resources. Many factors like geography, climate change, increasing populations, economic and technological ...
Treatment of spent engine oil (spent SAE W50) via solvent extraction- adsorption process for the production of transfer oil: Physico-chemical properties of the adsorbents
(
Elsevier
, 2023 , Article)
Regeneration of base oil from spent engine oil (spent SAE W50) for transfer oil production has been investigated using the solvent extraction-adsorption method. Solvent treated base oil regenerated from spent SAE W50 was ...
High-performance removal of toxic phenol by single-walled and multi-walled carbon nanotubes: Kinetics, adsorption, mechanism and optimization studies
(
Korean Society of Industrial Engineering Chemistry
, 2016 , Article)
The adsorption capabilities of two nano-sized adsorbents: multi-walled carbon nanotubes (MWCNTs) and single-walled carbon nanotubes (SWCNTs) were investigated for the removal of toxic phenol. The maximum adsorption capacities ...
Dual functional materials capable of integrating adsorption and Fenton-based oxidation processes for highly efficient removal of pharmaceutical contaminants
(
Elsevier
, 2023 , Article)
Pharmaceutical contaminants have shown widespread presence in water/wastewater threatening environmental and human health. Existing literature shows that adsorption can efficiently bind pharmaceuticals preventing their ...
Mesoporous and high-surface-Area activated carbon from defatted olive cake by-products of olive mills for the adsorption kinetics and isotherm of methylene blue and acid blue 29
(
Elsevier Ltd
, 2020 , Article)
The K2CO3 activation of defatted olive cake in N2 atmosphere was attempted for activated carbon (DOC-AC)
preparation to test its ability for the adsorption of methylene blue (MB) and acid blue 29 (AB 29). The optimum
conditions ...
Effective removal of phenol from wastewater using a hybrid process of graphene oxide adsorption and UV-irradiation
(
Elsevier B.V.
, 2022 , Article)
The focus of this work is the removal of phenol from water by graphene oxide (GO) nanoparticles, prepared by two different methods, through a hybrid adsorption?UV-irradiation process. The GO1 and GO2 were prepared using ...
The application of iron coated activated alumina, ferric oxihydroxide and granular activated carbon in removing humic substances from water and wastewater: Column studies
(
Elsevier B.V.
, 2010 , Article)
The efficiency of iron coated activated alumina, ferric oxihydroxide and granular activated carbon for the removal of humic substance (HS) from water and wastewater was demonstrated in batch studies. This paper investigated ...
