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 ...
Adsorptive Removal of Arsenic and Mercury from Aqueous Solutions by Eucalyptus Leaves
(
Springer International Publishing
, 2017 , Article)
The study is a first-time investigation into the use of Eucalyptus leaves as a low-cost herbal adsorbent for the removal of arsenic (As) and mercury (Hg) from aqueous solutions. The adsorption capacity and efficiency were ...
Impact of temperature and storage time on the migration of antimony from polyethylene terephthalate (PET) containers into bottled water in Qatar
(
Springer International Publishing
, 2017 , Article)
Prosperity in Qatar and the consequent stresses on water resources resulted in a sustainable increase in the bottled drinking water market. Reports on health concerns and possible migration of chemicals from the plastic ...
Mechanistic insights into the remediation of bromide ions from desalinated water using roasted date pits
(
Elsevier B.V.
, 2017 , Article)
Bromide ions (Br−) are associated with toxic by-products that might be produced during the disinfection of drinking water. The removal of Br− from water using roasted date pits (RODPs) and activated carbon was investigated. ...
Influence of composite particle formation on the performance and economics of grit removal
(
Elsevier Ltd
, 2017 , Article)
Grit is routinely removed at the headworks of municipal wastewater treatment works to limit its onerous impact on downstream processes. Grit separation technologies are normally based on sedimentation of a homogeneous ...
Investigation of the performance of biocompatible gas hydrate inhibitors via combined experimental and DFT methods
(
Academic Press
, 2017 , Article)
In this work, three ionic liquids (ILs) from the bio-compatible family of choline cations attached to anions of varying hydrophobicity namely: choline acetate (ChOAc), choline bistriflamide (ChNtf2), and choline chloride ...
Ionic liquids as dual functional inhibitors for natural gas hydrates (NGH)
(
AIChE
, 2017 , Conference Paper)
The thermodynamic inhibition (TI) and kinetic inhibition (KI) effect of pyrrolidinium based Ionic liquids (ILs) 1-Methyl-1-Propyl-pyrrolidinium Chloride [PM-Py][Cl] and 1-Methyl-1-Propyl-pyrrolidinium Triflate [PM-Py][Triflate] ...
Enhancing hydrate inhibition performance of biomolecules by doping with synergents
(
AIChE
, 2017 , Conference Paper)
The thermodynamic and kinetic inhibition effectiveness of the selected amino acids (AA): L-Alanine, Glycine, L-Histidine, L-Phenylalanine and L-Asparagine have been tested on the pure methane gas at different concentrations ...
Enhanced Adsorption of Selenium Ions from Aqueous Solution Using Iron Oxide Impregnated Carbon Nanotubes
(
Hindawi Limited
, 2017 , Article)
The aim of this research was to investigate the potential of raw and iron oxide impregnated carbon nanotubes (CNTs) as adsorbents for the removal of selenium (Se) ions from wastewater. The original and modified CNTs with ...
A comparative thermodynamic analysis of samarium and erbium oxide based solar thermochemical water splitting cycles
(
Elsevier Ltd
, 2017 , Article)
This paper reports a thermodynamic comparison between the samarium and erbium oxide based solar thermochemical water splitting cycles. These cycles are a two-step process in which the metal oxide is first thermally reduced ...
