Treatment of dairy effluents by electrocoagulation using aluminium electrodes.
The wastewaters treated by electrocoagulation differed by the fact that they exhibited a lower conductivity and a neutral pH value (by contrast to the acid nature of the solution treated by the chemical coagulation), which tends to show that it may be possible to recycle the treated water for some industrial uses.

Study of the removal of paraquat from aqueous solution by biosorption onto Ayous (Triplochiton schleroxylon) sawdust.
The batch biosorption of paraquat on Ayous (Triplochiton schleroxylon) sawdust was concerned with and the adsorption energy determined by the Dubinin-Radushkevich model was concluded to be mainly due to cation exchange. Expand
Investigation of the efficiency of a designed electrocoagulation reactor: Application for dairy effluent treatment
Abstract Here we present a new electrocoagulation reactor operating with 20 aluminum electrodes in bipolar configuration mode. The disposition and the orientation of the electrodes (tilted to form anExpand
Mercury(II) removal from water by electrocoagulation using aluminium and iron electrodes.
In this work, electrocoagulation was used to evaluate the treatment of synthetic solutions containing mercury(II) of concentration 2 x 10(-5)M. The effects of the distance between the electrodes,Expand
Preparation and characterization of charcoals that contain dispersed aluminum oxide as adsorbents for removal of fluoride from drinking water
Abstract Charcoals adsorbents that contain dispersed aluminum and iron oxides have been synthesized by impregnating wood with salt solutions followed by carbonization at 500 °C, 650 °C or 900 °C. TheExpand
Thiol-functionalized porous clay heterostructures (PCHs) deposited as thin films on carbon electrode : Towards mercury(II) sensing
Thiol-functionalized porous clay heterostructures (PCHs) have been prepared by intragallery assembly of mesoporous organosilica in natural smectite clay. The mesoporous framework was formed byExpand
Nanohybrid Kaolinite-Based Materials Obtained from the Interlayer Grafting of 3-Aminopropyltriethoxysilane and Their Potential Use as Electrochemical Sensors
The grafting of 3-aminopropyltriethoxysilane (APTES) onto the internal aluminol groups of two kaolinite minerals from Georgia and from Cameroon was achieved by utilizing their corresponding dimethylExpand
Preconcentration and voltammetric analysis of mercury(II) at a carbon paste electrode modified with natural smectite-type clays grafted with organic chelating groups
Abstract This study is devoted to the evaluation of a carbon paste electrode modified by a natural 2:1 phyllosilicate clay functionalized with either amine or thiol groups as a sensor forExpand
Evaluation of removal efficiency of fluoride from aqueous solution using new charcoals that contain calcium compounds.
Charcoals that contain calcium compounds have been synthesized by impregnating wood with calcium chloride followed by carbonization at 500 degrees C, 650 degrees C or 900 degrees C and were chemically stable in solution and the amount of dissolved Ca was found to be 3.23 mg L(-1) at neutral pH.
