    Abstract: A raw bentonite, obtained from Maghnia (Western Algerian) was impregnated into 1M ammonium chloride solution and thermally treated in a furnace at 200 °C during one hour. This treatment has improved its removal capacity of copper from aqueous solutions to about 30 %. The performances of the copper adsorption of this new material, after its physicoc... Show More

    Abstract: The sorption of Cu2+, Cd2+ and Pb2+ from aqueous solutions by unmodified (UBSH) and modified (MBSH) African breadfruit (Treculia africana) seed hull has been investigated. The amount of ions adsorbed by the hulls was dependent on the contact time range, 10 min – 120 min at optimum pH, 7.5 and temperature, 30 oC. Results revealed that the amount of ... Show More

    Abstract: In his study a new approach, the use of fuzzy logic type-2 in modeling biochemical reactions is shown. In fact, each enzymatic reaction is modeled by means of a "sigmoid transfer function" relating input and output substrate concentrations. The slant of this function is adjusted using fuzzy type-2. This adjustment is conducted depending on the enzy... Show More
