Article
Full-text available
In this work, the effective adsorption and the subsequent photodegradation activity, of TiO 2 brookite nanoparticles, for the removal of anionic dyes, namely, Alizarin Red S (ARS) and Bromocresol Green (BCG) were studied. Batch adsorption experiments were conducted to investigate the effect of both dyes' concentration, contact time, and temperature...
Article
Ibuprofen is one the most used non-steroidal anti-inflammatory drug, which is considered an emerging pollutant that may contaminate surface and underground water. Photodegradation using nanomaterials is one of the most sustainable and cheap technologies that can be used in water purification. In this study, the photodegradation efficiency of in-hou...

Tannery wastewater is considered one of the most contaminated and problematic wastes since it consists of considerable amounts of organic and inorganic compounds. These contaminants result in high chemical oxygen demand (COD), biochemical oxygen demand (BOD), and total suspended solids (TSS). In this work, the heterogeneous photodegradation of reca...

The growing accumulation of emerging contaminants in the environment can cause direct and indirect water pollution that puts human lives at risk. The fact that these contaminants are not or cannot be eliminated from the municipal water utilities, poses a significant concern. Researchers are currently pulling massive attention to improve existing te...
Article
In this study, the adsorptive removal of Zn²⁺, Cu²⁺, and Cr³⁺ metal ions from aqueous solutions onto NiO–MgO silica-based nanoparticles (SBNs) has been studied. The effect of several factors such as solution pH, initial concentration, contact time, and coexisting ions on the adsorbed amounts of single Zn²⁺, Cu²⁺, and Cr³⁺ ions have been investigate...
Conference Paper
Wastewater contains a variety of pollutants that are basically classified into organic such as dyes and inorganic substances. The contamination of surface and groundwater with synthetic dyes is a serious environmental problem and is a threat to human beings. These dyes could be cationic, anionic, or neutral. For instance, many industries use pigmen...
Conference Paper
Water contamination is a widespread problem that jeopardizing life on earth. The fact that water is capable of dissolving many different substances makes it uniquely vulnerable to pollution. Many human activities are causing direct and indirect water pollution such as landfill, industrial runoff, leaks and spills, mining, etc. Therefore, major step...

The competitive adsorption of cationic and anionic model molecules; methylene blue (MB) and acid red 88 (AR88), respectively, in aqueous solutions onto NiO and/or MgO SBNs was studied. Adsorption isotherms, kinetics and pH effect were investigated in batch modes. Computational modeling was conducted on Acclerys Material Studio for MB and AR88 adsor...

With the current state of affairs, the rapid population growth and development processes have led to a worsening water crisis. The decline in freshwater amounts is getting more progressively critical. It is actually becoming a cutting-edge issue due to the need for water to maintain life on earth. Therefore, turning wastewater into clean safe water...
Conference Paper
The energy demand is growing worldwide due to the increase in population and quality of life. Oil will continue to be a major source of current and future non-renewable energy. However, the current upgrading and recovery technologies are energy and water intensive. Hence new cost-effective technologies for enhancing upgrading and recovery of conven...
Conference Paper
The worldwide shortage of fresh water and the huge competing demands from variety of users stimulates an urgent need for finding alternative cost-effective and environmentally friendly wastewater treatment processes. For instance, synthetic dyes wastewater discharged from the textile and dyestuff industries poses an environmental alert since these...
Article
This study presents new environmentally sound and low-cost yet highly efficient pyroxene (NaFeSi2O6, PY), known as aegirine, nanoparticles. They are applied for the first time for the adsorptive removal of violanthrone-79 (VO-79) which was selected as a model-adsorbing compound to mimic polar heavy hydrocarbons. PY nanoparticles are prepared by a l...
Conference Paper
Canada’s oil sands industry produced 1.9 million barrels of bitumen per day in 2012, and it is expected to be doubled by 2022 to satisfy the continuous energy demand. The most effective extraction process of bitumen is steam assisted gravity drainage (SAGD), which is considered as one of the most commonly enhanced oil recovery (EOR) methods. Howeve...
Conference Paper
The demand of energy is increasing globally due to the explosive growth of population and industrialization. Hence, unconventional oil, like bitumen and heavy oil, is becoming one of the major future energy sources. In this context, heavy oil and bitumen, are gaining high popularity. One of the main components of bitumen are the polar heavy hydroca...
Conference Paper
Nanoparticle technology has recently emerged as a potential solution for a number of challenges facing the oil industry. Because of their unique features and special properties, nanoparticles could be used as adsorbents and catalysts for enhancing heavy oil quality. Our research group has used nanoparticle technology to integrate carbon rejection w...
Conference Paper
Alberta oil sands contain bitumen, a very viscous crude oil that requires intensive water and energy for its upgrading and recovery processes. In this matter, formidable challenges face bitumen and oil sands production including transportation, quality upgrading with lesser environmental footprints and economically feasible technologies. These chal...
Conference Paper

Organic pollutants and waste hydrocarbons present in industrial produced water pose a real environmental and energy conservation challenges in Alberta nowadays. Currently, for every barrel of Alberta's oil produced, approximately 4 barrels of produced water are generated. This produced water is typically a mix of water, sand, clay, small fraction o...
