Synoptic analysis of direct contact membrane distillation performance in Qatar: A case study
(
Elsevier B.V.
, 2015 , Article)
The aim of this study is to evaluate a bench scale direct contact membrane distillation (DCMD) performance using flat sheet polytetrafluoroethylene (PTFE) membrane at different inlet flow rates, temperatures, and salinity ...
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 ...
Removal of carbamazepine from water by a novel TiO2-coconut shell powder/UV process: Composite preparation and photocatalytic activity
(2013 , Article)
A novel TiO2-coconut shell powder (TCNSP) composite, prepared by the controlled sol-gel method with a subsequent heat treatment, was investigated as an innovative photocatalytic absorbent for the removal of carbamazepine ...
Phenol degradation by powdered metal ion modified titanium dioxide photocatalysts
(2012 , Article)
Conventional water purification and disinfection generally involve potentially hazardous substances, some of which known to be carcinogenic in nature. Titanium dioxide photocatalytic processes provide an effective route ...
A solid-phase extractant based on microemulsion modified date pits for toxic pollutants
(2013 , Article)
Application of microemulsion modified raw date pits as an inexpensive solid extractant for removing methylene blue (MB), copper ion (Cu2+) and cadmium ion (Cd2+) has been presented. The results summarised herein are also ...
Bioenergy II: Bio-ethanol from municipal solid waste (MSW): The role of biomass properties and structures during the ethanol conversion process
(
Berkeley Electronic Press
, 2010 , Article)
The emerging biofuel industry demands large amount of biomass feedstock. Although commercial ethanol has been produced from primary biomass sources such as corns, the global food crisis caused by the use of primary biomass ...
Kinetics of humics removal from water and wastewater using granular activated carbon, iron-coated activated alumina, and beta ferric oxihydroxide
(2010 , Article)
Application of kinetic models to represent the removal of humic substances from water and wastewater was investigated. An adsorbate-adsorbent system was represented by humic substances and three adsorbents, namely granular ...
Study on hydroxylammonium-based ionic liquids. II. Computational analysis of CO2 absorption
(
American Chemical Society
, 2011 , Article)
In the previous work of this series, we reported a wide experimental and computational analysis of the properties of hydroxylammonium-based ionic liquids. This family of ionic liquids shows very favorable economical, ...
Study on hydroxylammonium-based ionic liquids. I. Characterization
(
American Chemical Society
, 2011 , Article)
Two selected ammonium-based ionic liquids, 2-hydroxyethyltrimethylammonium l-(+)-lactate and tris(2-hydroxyethyl)methylammonium methylsulfate, were fully characterized. The most relevant thermophysical properties of pure ...
Thermodynamic assessment of effect of ammonia, hydrazine and urea on water gas shift reaction
(
Elsevier Ltd
, 2022 , Article)
In the present study, thermodynamic calculations have been carried out on water gas shift reaction in presence of some selected chemical additives such as ammonia, hydrazine, and urea to understand their impact on the ...
