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(...)

Preparation and Characterization of Clay Soils for Applications in Cyanide Removal from Mining Wastewater
Raymond Kaboré, Yacouba Sanou, Rasmane Tiendrebéogo, Alassance Compaoré, Adama Konaté, Samuel Paré
In Burkina Faso, water resources in mining areas are polluted by cyanide, which is released into the environment through mining activities. To mitigate this pollution, two clays named Koro and Kaya were collected in Burkina Faso and characterized using analytical technics. This work aimed to find out a cheap technology based on local soils for(...)

Antioxidant, Antifungal and Antitermite Activities of Residues from Hydrodistillation of Cymbopogon citratus, Eucalyptus camaldulensis and Mentha piperita
Assétou Sankara, Jean Claude Windéyolsidé Ouédraogo, Schémaéza Bonzi, Marie-France Thévenon, Yvonne Libona Bonzi-Coulibaly
Aromatic plant distillation produces residues rich in phenolic compounds known to be bioactive. In this context, residues from the hydrodistillation of Mentha piperita L., Cymbopogon citratus Stapf, and Eucalyptus camaldulensis Dehnh were chemically and biologically analyzed. The ethanol percentages (70%, 50%, and 30%) were evaluated by determ(...)
