Sorption of Bisphenol A as Model for Sorption Ability of Organoclays
S. Issaka Garikoé, Boubié Guel and Ingmar Persson
he arrangement of bisphenol A molecules into organoclays and their interactions with the intercalated surfactant were studied. The organoclays were prepared via solid-state intercalation of four cationic surfactants, such as dodecyltrimethyl-, tetradecyltrimethyl-, hexadecyltrimethyl-, and didodecyldimethyl-ammonium, as bromide salts, at diffe(...)

Flavonoid-Metallic Cation Interactions Studied by Antioxidant Potential of Mixtures in Methanolic Solution
HIEN Nabomo, OUEDRAOGO Jean Claude W., BONZI-COULIBALY Yvonne L.
Flavonoid-metal cation interactions were studied via antioxidant property evaluation with binary mixtures of 08
flavonoids with 10 metal cations at different concentrations. We have shown in the analysis by DPPH. Radical method, that despite different behaviors of metals, antioxidant capacity is reduced for some mixtures in methanolic solutio(...)

Effets de croissance de Cleome gynandra L. sur les teneurs en polyphénols et les activités antioxydantes des extraits
MANO Jonas, OUEDRAOGO Jean Claude W., HIEN Nabomo, DIALLO-KONE Martine, BONZI-COULIBALY Yvonne L.
Cleome gynandra L. est une plante alimentaire très prisée par les populations au Burkina Faso. Dans son utilisation traditionnelle, cette herbacée est bouillie et son eau de cuisson est non utilisée ; pourtant cette eau, qui n’est autre qu’un décocté aqueux, contient des métabolites spécifiques exploitables dans des applications biopesticides.(...)

Synthesis and study of physicochemical properties of a hybrid species : Iron phthalocyanine –silver nanoparticles
Lassané Tarpaga, Bintou Sessouma, Seydou Ouédraogo, Vincent Colliere, Mabinty Bayo-Bangoura, Catherine Amiens, Karifa Bayo.
This article reports a strategy to synthesize a hybrid species made of iron phthalocyanine (FePc) grafted to the surface of silver nanoparticles. The affinity between sulfur and silver on the one hand, and the aptitude of the FePc complex to bind pyridine axially on the other, allowed us to use thiopyridine as a linker between the two entities(...)

Kinetic and Thermodynamic Study of Cr(Vi) Removal in Water Using Activated Carbons Prepared from Orange Peels.
Alfa-Sika Mande Seyf-Laye, Sanou Yacouba, Tchakala Ibrahim, Sedou Moudassirou, Djaneye-Boundjou G, Moctar L. Bawa, Honghan Chen
This work was focused on the removal of hexavalent chromium from artificially contaminated
aqueous solutions using Orange peels as an adsorbent. Batch experiments were carried out in order to determine
the kinetics and the adsorption isotherms of the process. The influence of experimental variables such as the pH,
the temperature, the amoun(...)

Characterization of sugar cane bagasse ash from Burkina Faso for cleaner cement production: Influence of calcination temperature and duration
Moussa Ouedraogo, Moustapha Sawadogo, Issiaka Sanou, Michel Barro, Sory Nassio, Mohamed Seynou, Lamine Zerbo
In this study, the sugar cane bagasse from Burkina Faso has been calcined at temperatures ranging from 550 to 750 °C with a heating stage of 2 or 3 h to produce pozzolanic ashes as supplementary cementitious materials for eco-cement production. The ashes obtained were subsequently characterized for their chemistry, mineralogy, and pozzolanic a(...)
