Evaluation of 3-methyl-4-nitrophenol a pesticide by-product removal from water using nanofiltration combined by Trichoderma harzianum microbial fuel cell for irrigation purposes
Jean‑Philippe Théodore Silga, Yibor Fabrice Roland Bako, Nesrine Kalboussi, Maxime Pontié, Serge Mbokou Foukmeniok, Mehri Shabani, Issa Tapsoba
Fenitrothion is an organophosphorus insecticide widely used in Sahelian countries. However, fenitrothion undergoes rapid degradation, generating many by-products, the main one being 3-methyl-4-nitrophenol (MNP) known to be hazardous for humans and the environment. The intensive use of fenitrothion has led to environmental contamination, raisin(...)

Electrochemical Behavior of Copper on Unmodified GlassyCarbon in Chloride-Containing Nitric Acid Media
Hamidou Kaboré, Tambi Ramdé, Fousseni Soma, Lucien Bonou
This study has been conducted on the electrochemical behavior of copper in chloride-containing nitric acid media by cyclic voltammetry, chronoamperometry, and chronopotentiometry. The results showed that the diffusion process controls the copper reduction process on the glassy carbon. A typical current transient of progressive nucleation and t(...)

Physicochemical and Mineralogical Characterizations of Two Natural Laterites from Burkina Faso: Assessing Their Potential Usage as Adsorbent Materials
Corneille Bakouan, Louise Chenoy, Boubié Guel, and Anne-Lise Hantson
In the framework of lateritic material valorization, we demonstrated how the geological environment determines the mineralogical characterizations of two laterite samples,
KN and LA. KN and LA originate from the Birimian and Precambrian environments, respectively. We showed that the geological criterion alone does not determine the applicabil(...)
