In this study, removal of methylene blue by electro-coagulation method using aluminum and iron electrodes was investigated. The influence of the operating parameters such as contact time, current density, anode type, inter-electrodes distance, initial and final pH and energy consumption rate was determined. Dye removal was increased with increases in solution pH, current density and c...

This work reports on the viability of the electroflocculation (EF) process for chemical oxygen demand (COD), turbidity and color removal from a raw effluent originated from a particular textile industry related to hemp manufacture. Firstly, the following operational parameters were optimized: current density; initial pH; electrolysis time; material of the electrode (iron, aluminum or iron-alumi...

Background & objectives: Nitrate contamination of drinking water is a common problem in many parts of the world that poses a serious threat to public health and environment. In this research, the performance of a new rotary electrocoagulation reactor model for removal of nitrate in presence or absence of turbidity has been investigated. Methods: In this study, aluminum and iron electrodes were...

Passivation Phenomena have been observed upon cathodic and anodic polarization of the Al electrode in AlC 13-KCl-NaC1 melts between 100 and 160 °C. They are caused by formation of a solid salt layer at the electrode surface resulting from concentration changes upon current flow. The anodic limiting currents increased with temperature and with decreasing AlCl content of the melt. Current voltage...

In this research, the efficiency of electrocoagulation treatment process using iron and aluminum electrodes to treat synthetic wastewater containing Reactive Red 24 (RR 24) was studied. The effects of parameters such as current density, pH, type of electrolyte, initial dye concentration, electrolyte concentration, temperature, and inter electrode distance on dye removal efficiency were investig...

in this research, an enzyme modified electrode has been produced during the electropolymerization of aniline through incorporation of sulfite oxidase into a conducting polymer. then the bioelectrochemical response of resulted sulfite biosensor was investigated at different experimental conditions. study of  the stability of the resulted sulfite biosensor revealed that formation of a passive fil...
