Sibiry Albert Kaboré, Emmanuelle Quillérou, Stéphanie Maiga-Yaleu, Maguette Kairé, Ibrahim Bouzou Moussa, Oumarou Malam Issa, Damien Hauswirth, Hassan Bismarck Nacro
Techniques of degraded ecosystems restoration in the Sahel have largely contributed to slowing down desertification
process. However, they are often very costly, requiring important manpower and financial resources. The
economic benefits of such cases of land restoration are under-documented, especially in scientific literature. The
aim of(...)

Study of the Efficiency of Two Clays Soils for Cyanide Removal in Water: Kinetic and Equilibrium Modelling
Raymond KABORE, Yacouba SANOU, Adama KONATE, Samuel PARE
In Burkina Faso, water resources in mining area are sometime polluted by cyanide. To mitigate this pollution, clays have been collected in Kaya and Koro and used as adsorbents to remove cyanide in waters. Experiments have been carried out using batch adsorption with synthetic cyanide solutions. The influence of operating conditions has been ev(...)
