Algal toxins and producers in the marine waters of Qatar, Arabian Gulf
( Elsevier Ltd , 2016 , Article)Harmful Algal Bloom species are ubiquitous and their blooms occur in the Arabian Gulf. In this study, two cruises were performed in 2012 and 2013 to collect phytoplankton samples from 4 sites in the Arabian Gulf. Toxin ... -
Electrochemical oxidation of ammonia (NH4+/NH3) ON synthesized nickel-cobalt oxide catalyst
( Elsevier Ltd , 2021 , Article)Ni–C and Co/Ni–C electro-catalysts were prepared using solvothermal reaction method and used to oxidize ammonia in aqueous solution. Ni and Co were consistently dispersed in carbon generating spherical and porous structure ... -
Electrochemical oxidation of ammonia on nickel oxide nanoparticles
( Elsevier Ltd , 2019 , Article)NiO and NiOTiO2 nano-catalysts were synthetized using solution combustion synthesis (SCS) method and tested toward ammonia oxidation in synthetic and real wastewater. As-synthesized NiO nano-catalyst showed a tightly ... -
Eutrophication in the coastal waters of Alexandria following the increase in phosphorus load
( Parlar Scientific Publications , 1996 , Article)Samples from the coastal waters of Alexandria during 1991-1993 indicate a remarkable increase in the phosphorus load from 870 to 1140 kg y-1 compared to 567 kg y-1 in 1986 raising the average phosphorus from 1.01 to 1.47 ... -
Study the efficiency of Ultrasonic Technology in Removal of Algae from Surface Waters
( Qatar University Young Scientists Center - Qatar University , 2024 , Conference Paper)The diversity of human activities and the expansion of agricultural work led to an increase in nutrient accumulation, which reached aquatic ecosystems, causing algal blooms. This highlighted the importance of the treatment ...
