Phosphate removal from wastewater by electrocoagulation using aluminium electrodes

Abstract: The removal of phosphate from wastewater by electrocoagulation using aluminum electrodes was investigated The main objectives of the experiments were to investigate the effects of the various operating parameters, such as current density, Electrocoagulation(EC)duration, initial phosphate concentration, temperature, pH of the solution, salt (NaCl) concentrations and electrolyte type [NaCl, KCl, NaNO 2, NaNO 3 ] on the phosphate removal efficiency from synthetic wastewater in batch EC process The ranges of experimental parameters were between 10 and 150 mg PO 4/L for initial phosphate concentration, 3–10 for initial pH of the wastewater, 05–5 g NaCl/L for supporting electrolyte concentration, 2g/L of other supporting electrolytes KCl, NaNO 3, NaNO 2 and 113–454 mA/cm 2 for current density The results showed that the maximum removal efficiency was achieved at a current density of 454mA/cm 2 , at a pH of 70 and 4-5 g/L NaCl

Effect of electrode material and supporting electrolyte on the treatment of water containing Escherichia coli by electrocoagulation

Abstract: Laboratory experiments were carried out to investigate the mechanisms of electrochemical disinfection of artificial wastewater contaminated by Escherichia coli culture (5 × 105 UFC/100 mL) using electrocoagulation. In order to go deeply into the mechanism of the process, the behaviors of two dissolved-type electrodes (ordinary steel and aluminum) and a non-dissolved-type (carbon graphite) electrode were compared. The ordinary steel electrode was found more efficient for E. coli cells destruction compared to aluminum and carbon graphite electrodes. In order to determine the most favorable condition for the treatment, the effect of various supporting electrolytes including, sodium chloride, sodium sulfate and sodium nitrate, was scrutinized. E. coli is inactivated by 5 log units for a charge loading of 37.30 F/m3 for sodium sulfate, 24.87 F/m3 for sodium nitrate and 12.43 F/m3 for sodium chloride. It thus appears that the most favorable supporting electrolyte type for this method of disinfection is sodium chloride, a fact which can be explained by the formation of disinfectant by-products such as chlorine dioxide, hypochlorite ions and perchlorate ions. From the results obtained, electrocoagulation applied to the elimination of E. coli proceeds through three combined effects: the electric field, the actions of oxidants electrogenerated during the process and the adsorption by the metallic hydroxides formed in solution.

Process for synthesizing ionic metal complex

Abstract: The invention relates to a process for synthesizing an ionic metal complex represented by the general formula (1) or (5). This process includes reacting in an organic solvent a compound (corresponding to ligand of the complex) represented by the general formula (2) or (6) with a halogen-containing compound represented by the general formula (3) or (4), in the presence of a reaction aid containing an element selected from the group consisting of elements of groups 1-4 and 11-14 of the periodic table. It is possible by this process to easily and efficiently synthesize the ionic metal complex, which can be used as a supporting electrolyte for electrochemical devices, a polymerization catalyst of polyolefins and so forth, or a catalyst for organic synthesis.
