Eco-structured biosorptive removal of basic fuchsin using pistachio nutshells: A definitive screening design-based approach
El-Azazy M.; El-Shafie A.S.; Ashraf A.; Issa A.A. ( MDPI AG , 2019 , Article)Biosorptive removal of basic fuchsin (BF) from wastewater samples was achieved using the recycled agro-wastes of pistachio nut shells (PNS). Seven adsorbents were developed; raw shells (RPNS) and the thermally activated ... -
Kinetics of alkoxysilanes hydrolysis: An empirical approach
Issa A.A.; El-Azazy M.; Luyt A.S. ( Nature Research , 2019 , Article)Alkoxysilanes and organoalkoxysilanes are primary materials in several industries, e.g. coating, anti-corrosion treatment, fabrication of stationary phase for chromatography, and coupling agents. The hydrolytic polycondensation ... -
Polymerization of organoalkoxysilanes: Kinetics of the polycondensation progress and the effect of solvent properties and salts addition
Issa, A. A.; El-Azazy, M.; Luyt, A. S. ( Elsevier B.V. , 2020 , Article)The kinetics and the produced oligomer patterns of organoalkoxysilanes (AS) were investigated under different conditions by using gas chromatography (GC), because the degree of the polymerization and the siloxane conformations ... -
Pomegranate peels as versatile adsorbents for water purification: Application of box–behnken design as a methodological optimization approach
El-Azazy M.; Kalla R.N.; Issa A.A.; Al-Sulaiti M.; El-Shafie A.S.; Shomar B.; Al-Saad K.... more authors ... less authors ( John Wiley and Sons Inc. , 2019 , Article)Pomegranate peels (PGP) were tested as a green adsorbent for the removal of Ni(II) from contaminated water samples. Both raw (RPG), and char/burnt peels (BPG) were tested. A multivariate analysis approach, Box–Behnken (BB) ... -
Recycling of Date Pits Into a Green Adsorbent for Removal of Heavy Metals: A Fractional Factorial Design-Based Approach
Al-Saad K.; El-Azazy M.; Issa A.A.; Al-Yafie A.; El-Shafie A.S.; Al-Sulaiti M.; Shomar B.... more authors ... less authors ( Frontiers Media S.A. , 2019 , Article)Date pits (DPs) have been recycled into a low-cost adsorbent for removing of selected heavy metals (HMs) from artificially contaminated aqueous solutions. Adsorption of targeted HMs, both by raw date pits (RDP) and burnt ... -
Smart Synthesis of Trimethyl Ethoxysilane (TMS) Functionalized Core–Shell Magnetic Nanosorbents Fe3O4@SiO2: Process Optimization and Application for Extraction of Pesticides
Al-Saad K.; Issa A.A.; Idoudi S.; Shomar B.; Al-Ghouti M.A.; Al-Hashimi N.; El-Azazy M.... more authors ... less authors ( MDPI AG , 2020 , Article)In the current study, a smart approach for synthesizing trimethyl ethoxysilane–decorated magnetic-core silica-nanoparticles (TMS-mcSNPs) and its effectiveness as nanosorbents have been exploited. While the magnetite core ...
