Removal of manganese (II) in water samples by the aerationfiltration process and determination based on 5-Br-PADAP ligand by cathodic stripping voltammetry
Abdoulkadri Ayouba Mahamane, Boubié Guel, Paul Louis Fabre
In this study, manganese (Mn II) was determined in aqueous media by an electrochemical method, and its removal was evaluated using the aeration-filtration process (AFP). An electrochemical sensor based on carbon paste (EPC) modified with the 5-Br-PADAP ligand was used to measure Mn (II) in aqueous media. Through the optimization of
analytical(...)

Transfer of Bisphenol A and Trace Metals from Plastic Packaging to MineralWater in Ouagadougou, Burkina Faso
Boukary Sawadogo, Francis Ousmane Konaté, Yacouba Konaté, Ousmane Traoré, Seyram Kossi Sossou, Eric Sawadogo, Pane Bernadette Sourabié Ouattara, Harouna Karambiri
The consumption of packaged water is growing rapidly in both urban and rural centres in Burkina Faso. Bisphenol A (BPA) and trace metals are among the compounds used in the manufacture of plastic packaging, and their presence in water can pose a health risk to consumers due to their alleged toxicity. Therefore, this study explores the transfer(...)

Soungalo Ouattara, Brahima Sorgho, Lamine Zerbo, Youssouf Sawadogo, Moustapha Sawadogo, Mohamed Seynou, Philippe Blanchart
Geopolymers based on clay materials from Burkina Faso were developed and then characterized for use in
construction. The results of the characterization of the clay mineral material referenced TAN as well as its calcined
forms TAN 700 and TAN 800 have shown by several analysis techniques (DRX, IR, ICP-AES) that TAN contains
kaolinite (71%),(...)
