Autor: Abdelhak Moumen, Zhour Hattab, Youghourta Belhocine, Kamel Guerfi, Nacer Rebbani
Publikováno v: Bulletin of Chemical Reaction Engineering & Catalysis, Vol 14, Iss 2, Pp 294-300 (2019)
In this work, a non-toxic protonated kaolin clay exchanged with protons, was successfully applied as a solid acid catalyst for the polymerization of tetrahydrofuran (poly(THF)) at room temperature in the presence of acetic anhydride. Prior to using t

Autor: Ridha Djellabi, Kamel Guerfi, Alain Iost, Alex Montagne, Mamoun Fellah, Kirill Borodin, Naouel Hezil, Aleksei Obrosov
Publikováno v: Environmental science and pollution research international. 28(6)
Surfactants are widely used in many chemical industries and as primary components of cleaning detergents due to their specific characteristics, which in turn results in high pollution of domestic and industrial wastewaters by such substances. In this

Elimination of Chromium (VI) by Adsorption onto Natural and/or Modified Kaolinite
Autor: Omar Assala, Kamel Guerfi, Nouel Hezil, Mohamed Zine Touhami, Mamoun Fellah
Publikováno v: Diffusion Foundations. 18:106-112
The purpose of this study is to compare the effectiveness of a natural and / or modified kaolinite to adsorb chromium-containing aqueous effluents in its most toxic form (the hexavalent chromate ion (Cr (VI)). Adsorbant used in the present study is a

Valorization of granulated slag of Arcelor-Mittal (Algeria) in cationic dye adsorption from aqueous solution: column studies
Autor: Zhour Hattab, Kamel Guerfi, Naima Filali, Radia Mazouz
Publikováno v: Journal of Water Reuse and Desalination. 6:204-213
A continuous adsorption study in a fixed-bed column was carried out using granulated slag (GS) as an adsorbent for the removal of methylene blue (MB) from aqueous solution. The effects of various parameters, such as initial dye concentration, flow ra
