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: ... -
Enhancement of the corrosion resistance of mild steel with femtosecond laser- nanostructuring and CrCoNi medium entropy alloy coating
Ahmad, Shahbaz; Ahmad, Waqas; Abu Baker, Aya; Egilmez, Mehmet; Abuzaid, Wael; Orhan, Mehmet Fatih; Ibrahim, Taleb; Khamis, Mustafa; Alnaser, Ali (Elsevier, 2022)In this work, the corrosion resistance of mild steel surface nanostructured with a femtosecond laser and coated with high corrosion resistant CrCoNi (CCN) medium entropy alloy through magnetron sputtering is studied. ... -
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 ...
