Fluoride excess in drinking water is noticed many countries around the world and particularly Senegal where, addition to fluoride excess, high levels of salinity are also encountered. In order reduce groundnut basin Senegal, two types clays namely montmorillonite KSF K10 as well were used adsorbent materials. The results show that pH which was initially alkaline becomes acidic varying from 2.80...

The synthesis of novel 6,6'-methylene-bis-[3-(2-anilinoacetyl)-4-hydroxycoumarin] derivatives 6a-f was achieved in excellent yields from 6,6'-methylene-bis-[3-(2-bromoacetyl)-4-hydroxycoumarin] 5 and various arylamines. 5,5'-Methylene-bis-ethylsalicylate 3 was obtained by the esterfication of 5,5'-methylene-bis-salicylic acid 2 with ethanol, which was in turn obtained from salicylic acid 1 and ...

Production of fatty acid esters from stearic, oleic, and palmitic acids and short-chain alcohols (methanol, ethanol, propanol, and butanol) for the production of biodiesel was investigated in this work. A series of montmorillonite-based clays catalysts (KSF, KSF/0, KP10, and K10) were used as acidic catalysts. The influence of the specific surface area and the acidity of the catalysts on the es...

The sonocatalytic performance of the synthesized TiO2/Montmorillonite K10 (TiO2/MMT) nanocomposite was studied in removal of Basic Blue 3 (BB3) from water. The TiO2/MMT nanocomposite was prepared by hydrothermal method. Scanning electron microscope, X-ray diffraction and Fourier transform infrared were used to characterize the synthesized nanocomposite. The average size of TiO2 nanoparticles de...
