Pollution chimique des eaux de surface liée aux activités agricoles autour des retenues d’eaux au Nord du Burkina Faso
S. B. Maïga-Yaleu, A. D. H., B. Guel
L’une des préoccupations mondiales en matière environnementale est la pollution des eaux de surface par les activités agricoles. En effet, dans le secteur agricole, de grandes quantités de produits chimiques tels que les engrais, les pesticides sont utilisés pour améliorer le rendement agricole et lutter contre les espèces nuisibles aux plante(...)

Synthesis, Characterization, Crystal Structure and Quantum Chemical Calculations of 2-oxo-2H-chromen-3-yl Acetate
Akoun Abou, Siaka Sosso, Affiba Florance Kouassi, Thouakesseh Jeremie Zoueu, Abdoulaye Djande, Olivier Ouari
This paper is focused on a combined experimental and theoretical study of 3-substituted coumarin derivative, the 2-oxo-2H-chromen-3-yl acetate (I). The compound was synthesized by reacting chroman-2,3-dione and acetic anhydride in dried diethyl ether in the presence of dried pyridine and crystallized in the orthorhombic crystal system with Pbc(...)

SOLID-STATE SYNTHESIS AND PHYSICO-CHEMICAL CHARACTERIZATION OF MODIFIED SMECTITES USING NATURAL CLAYS FROM BURKINA FASO
Issaka Garikoé, Brahima Sorgho, Boubié Guel and Ingmar Persson
Solid-state intercalation was applied to prepare organo-smectites using cationic surfactants and natural clays containing smectite at various surfactant/smectite ratios. The surfactants enter the interlayers of smectites causing a swelling of the clays. The used clays were collected in Siétougou and Diabari villages located in the eastern part(...)

Formulation of clay refractory bricks: influence of the nature of chamotte and the alumina content in the clay
Moustapha Sawadogo, Mohamed Seynou, Lamine Zerbo, Brahima Sorgho, Gisèle Laure Lecomte-Nana, Philippe Blanchart, Raguilnaba Ouédraogo
Abstract: Refractory materials from kaolinitic clays and clay chamotte or quartz were studied to increase the refractoriness
under load at temperature above 1300°C. Two different clays mined in Burkina Faso were used and chamotte grains were
obtained by preliminary firing a local clay. Fired materials at 1350-1400°C present a typical granu(...)

Variation spatiale des ions majeurs en solution sous l’impact des croûtes de surface dans le Sahel du Burkina Faso
Stéphanie Batchakoue Maïga-Yaleu, HammaYacouba
L’objectif de cette étude est d’évaluer le rôle des croûtes de surface du sol sur les pertes en matières dissoutes par les eaux de ruissellement. Les données ont été collectées durant 3 années consécutives sur des parcelles de 1 m², 50 m² et 150 m² installées sur les croûtes structurale (STRU), d’érosion (ERO), gravillonnaire (GRAV) et de dess(...)

Removal of bisphenol A by adsorption on organically modified clays from Burkina Faso
Issaka Garikoé , Brahima Sorgho , Adama Yaméogo , Boubié Guel & Dickson Andala
Four cationic surfactants with various length and number of long alkyl chains such as dodecyltrimethylammonium, tetradecyltrimethyl-ammonium, hexadecyltrimethylammonium and didodecyldimethyl-ammonium were intercalated at different concentrations into two natural clays from Burkina Faso via solid-state reaction. Each organoclay was used to expl(...)

Green Analytical Methods of Antimalarial Artemether-Lumefantrine Analysis for Falsification Detection Using a Low-Cost Handled NIR Spectrometer with DD-SIMCA and Drug Quantification by HPLC
Moussa Yabré , Ludivine Ferey , Abdoul Karim Sakira , Camille Bonmatin , Clotilde Fauré , Touridomon Issa Somé and Karen Gaudin
Abstract: Two green analytical approaches have been developed for the analysis of antimalarial
fixed dose tablets of artemether and lumefantrine for quality control. The first approach consisted
of investigating the qualitative performance of a low-cost handheld near-infrared spectrometer
in combination with the principal component analysis(...)

Chemical Profil and Anti-termite Activity of Hydrodistillation Residues From Three Aromatic Plants Acclimated in Burkina Faso
Assétou Sankara, Jean Claude W. Ouédraogo, Luc Pignolet, Marie-France Thévenon & Yvonne L. Bonzi-Coulibaly
Distillation process of aromatic plants produces a considerable amou t of solid residues, which are rich in secondary métabolites known as bioactive compounds. In this context, residues from hydrodistillation of selected Aromatic plants such as Mentha piperita L., Cymbopogon citratus Stapf and Eucalyptus camaldulensis Dehnh, have been studied(...)

Modulating the electrical properties of organic heterojunction devices based on phthalocyanines for ambipolar sensors
Seydou Ouedraogo, Rita Meunier-Prest, Abhishek Kumar, Mabinty BayoBangoura, and Marcel Bouvet
Although ambipolar materials are highly studied in organic electronics, they are rarely used in gas sensors. In
the present work, we studied ammonia sensing on organic heterojunctions in a bilayer configuration composed of
octachlorinated metallophthalocyanines (M(Cl8Pc); M: Co, Cu and Zn) as a sublayer and lutetium bis-phthalocyanine (LuPc2(...)

Development and validation of an original magneto-chromatography device for the whole blood determination of hemozoin, the paramagnetic malaria pigment
Orokia Traore, Moussa Compaore, Philippe Okusa, François Hubinon, Pierre Duez, Bertrand Blankert, Martin Kindrebeogo
Background: Malaria remains the first global parasitic endemic disease with more than 400,000 deaths per year;
there is a definite need for prevention measures and treatments, but also for rapid and low-cost diagnostic methods. Hemozoin, a detoxification polymer formed from heme by the parasite, and a likely biomarker of infection, has entice(...)
