Cyclic Sequential Removal of Alizarin Red S Dye and Cr(VI) Ions Using Wool as a Low-Cost Adsorbent
Khamis, Mustafa; Ibrahim, Taleb; Jumean, Fawwaz; Sara, Ziad; Atallah, Baraa (MDPI, 2020)Alizarin red S (ARS) removal from wastewater using sheep wool as adsorbent was investigated. The influence of contact time, pH, adsorbent dosage, initial ARS concentration and temperature was studied. Optimum values were: ... -
Removal of lead ions from wastewater using multi walled carbon nanotubes modified with sodium lauryl sulfate
Suliman, Malaz; Ibrahim, Taleb; Jumean, Fawwaz; Khamis, Mustafa; Sabri, Muhammad Ashraf (Desalination Publications, 2017-12)Multi walled carbon nanotubes (MWCNTs) modified with sodium lauryl sulfate (SLS) were synthe-sized, characterized and successfully used for the removal of Pb2+ from aqueous solutions. Adsorp-tion results revealed that this ... -
Removal of Pb(II) from Aqueous Solutions by Zeolites, Porcelanite and Sands: Correlation of Morphology and Chemical Composition to Batch Removal Efficiency
Jumean, Fawwaz; Pappalardo, Lucia; Khoury, Hani (Scientific Research Publishing, 2015-03)Chemical compositions of natural zeolites, porcelanite (opal-CT) and local sands were determined by X-ray fluorescence (XRF) and correlated with their Pb(II) removal efficiencies. Zeolites and porcelanite were from the ... -
Scale-Up of Self-Regenerating Semi-Batch Adsorption Cycles through Concurrent Adsorption and Reduction of Cr(VI) on Sheep Wool
Badrelzaman, Mohamed; Khamis, Mustafa; Ibrahim, Taleb; Jumean, Fawwaz (MDPI, 2020)A previous publication by our group reported that adsorption of Cr(VI) on sheep wool reached 99% when allowed a long residence time, with concurrent reduction to Cr(III). In this study, the process was scaled up by optimizing ...
