Bio-Waste Aloe vera Leaves as an efficient adsorbent for Titan Yellow from Wastewater: Structuring of a novel adsorbent using Plackett-Burman factorial design
El-Azazy M.; Dimassi S.N.; El-Shafie A.S.; Issa A.A. ( MDPI AG , 2019 , Article)Titan yellow (TY), a triazene azo dye, was removed from contaminated wastewater samples using a green adsorbent recycled from Aloe vera leaves (AV) waste. Two adsorbents were developed-air-dried Aloe vera (ADAV) and thermally ... -
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 ... -
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 ...
