Evaluation of the current state and perspective of wastewater treatment and reuse in Qatar
(
Desalination Publications
, 2017 , Article)
In Qatar, many freshwater resources have already been depleted due to the overconsumption as a result of the population and economic growth. Moreover, due to the lack of sufficient sewage treatment infrastructure, Qatar ...
Solar photocatalytic degradation of 2-chlorophenol with ZnO nanoparticles: optimisation with D-optimal design and study of intermediate mechanisms
(
Springer Verlag
, 2017 , Article)
In this study, the photocatalytic degradation of toxic pollutant (2-chlorophenol) in the presence of ZnO nanoparticles (ZnO NPs) was investigated under solar radiation. The three main factors, namely pH of solution, solar ...
Reaction Kinetics of Carbon Dioxide (CO2) with Diethylenetriamine and 1-Amino-2-propanol in Nonaqueous Solvents Using Stopped-Flow Technique
(
American Chemical Society
, 2016 , Article)
In this work, the reaction kinetics of carbon dioxide (CO2) with diethylenetriamine (DETA) and 1-amino-2-propanol (1-AP) in methanol and ethanol systems were measured using the stopped flow technique over a temperature ...
Effects of amphiphilic pluronic F127 on the performance of PS/SPEEK blend ultrafiltration membrane: Characterization and antifouling study
(
Elsevier Ltd
, 2017 , Article)
The effect of amphiphilic Pluronic F127 additive on the ultrafiltration performance of polysulfone (PSf)/sulfonated poly (ether ether ketone) (SPEEK) blend flat sheet membranes was investigated in the present work. Fixed ...
Effects of sodium carbonate addition, heat and agitation on swelling and rheological behavior of Ca-bentonite colloidal dispersions
(
Elsevier Ltd
, 2017 , Article)
The effects of the addition of sodium carbonate (Na2CO3) and the subsequent simultaneous heating and stirring on the rheological behavior of Ca-bentonite colloidal dispersions have been investigated in this study. Ca-bentonite ...
Synthesis and characterisation of Co2+-incorporated ZnO nanoparticles prepared through a sol-gel method
(
Elsevier B.V.
, 2016 , Article)
The properties of ZnO nanoparticles were modified by doping them with cobalt ions (Co2+) in various compositions through a sol-gel route. The Co2+-doped ZnO nanoparticles were characterised using X-ray diffraction (XRD), ...
Heat duty, heat of absorption, sensible heat and heat of vaporization of 2–Amino–2–Methyl–1–Propanol (AMP), Piperazine (PZ) and Monoethanolamine (MEA) tri–solvent blend for carbon dioxide (CO2) capture
(
Elsevier Ltd
, 2017 , Article)
Chemical absorption using reactive amines for carbon dioxide (CO2) capture is characterized by absorption heat, heat of desorption and heat duty for regeneration (Qreg, kJ/mol CO2). This study experimentally investigated ...
Development of polysulfone-nanohybrid membranes using ZnO-GO composite for enhanced antifouling and antibacterial control
(
Elsevier B.V.
, 2017 , Article)
Zinc oxide nanoparticles were well-known for the enhanced antifouling and antibacterial properties which could be beneficial for membrane processes in desalination. The functionalization of ZnO onto graphene oxide nanoplates ...
