The effect of solids on the electrochemical treatment of olive mill effluents

Journal of Chemical Technology & Biotechnology, 2007
AbstractThe electrochemical oxidation of an olive mill effluent over Ti–Pt anodes was studied. The effluent had an average total chemical oxygen demand (COD) value of 234 g L−1, soluble COD of 61 g L−1, soluble phenolic content 3.4 g L−1, total solids of 80 g L−1 and pH = 5.1.

Ball milling synthesis of LixTiP4: Improvement of the electrochemical performances

Ionics, 2003
While promising performance as a negative electrode in Li-ion batteries, with flat voltage profiles at about 1 V and large specific capacities, today’s drawback with LixTiP4 materials is the difficulty encountered in preparing single-phase powders. To alleviate this issue, new synthetic routes have been investigated and we present here our results ...

Electrochemical treatment of olive oil mill wastewater.

Annali di chimica, 2001
The possibility of oxidizing at a PbO2 anode the phenols and polyphenols, present in the olive oil mill wastewater, has been studied as a pretreatment for the submission of such wastewater to the traditional biological treatments. The results obtained operating at current densities ranging 500 to 2000 A/m2 show that it is possible to reduce the ...

Enhanced electrochemical properties of ball-milled Mg2Ni electrodes

International Journal of Hydrogen Energy, 2002
Abstract The characteristics and mechanisms of enhanced electrochemical properties for a Mg 2 Ni alloy produced by a ball-milling treatment were investigated by electrochemical measurements and XRD analysis. The particle size decreases, the internal strain increases, and the alloy gradually becomes amorphous on ball-milling.

The structure and electrochemical properties of ball-milled Ti0.9Zr0.2Mn1.6Ni0.2V0.2 alloys

Solid State Ionics, 2002
Abstract The high-energy ball-milling technique is generally used to modify the surface structure and texture of materials in order to improve their physical or chemical properties. In the conditions of thermodynamic equilibrium, the hydrogen-storage capacity of Ti0.9Zr0.2Mn1.6Ni0.2V0.2 alloy can reach 240.9 ml/g, from which it can be calculated that
