abstract background: heavy metals in industrial wastewater especially chromium (vi) are considered as the main environmental pollutants. methods: electrochemical cell made of plexiglass with a volume of 1.95 lit was used. iron and graphite electrodes, electricity conductor, each with dimensions of 0.1×3×10 cm (width×length×height) were designed and built. tests were carried out in various condi...

concurrent renewable energy production and wastewater treatment are two main reasons for using microbial fuel cells (mfcs). in this study, real wastewater was used for treating and power generation by air cathode microbial desalination cells (acmfc). the total duration of voltage generation by acmfc was about 151.9 ±23.2 h. the maximum voltage produced from municipal wastewater treatment was 27...

the aim of this study was to determine the feasibility of coupling an electrochemical process with a biological treatment in order to degrade phosmet, an organophosphorous pesticide. the absence of biodegradability of phosmet by pseudomonas fluorescens and activated sludge was verified in our operational conditions. so, a conventional biological treatment is not appropriate for phosmet polluted...

von Euler, H., 2002. Electrochemical treatment of tumours. Doctor’s dissertation. ISSN 1401-6257, ISBN 91-576-6386-6. By electrochemical treatment (EChT) neoplastic tissue is supplied with a continuous direct current through two or more electrodes placed in or near the tumour. The EChT has been taken under serious consideration as being one of several techniques for local treatment of malignanc...

according to environmental protection organization of iran, maximum permissible concentration of residual phosphorus in treated municipal wastewater is 1 mg /l-p. the total average phosphorus concentration in raw municipal wastewater is about 8 mg / l; about 70 percent of the incoming phosphorus normally is discharged with secondary treatment plant effluents. in this research, the role of addin...

Electrochemical treatment is an alternative modality for tumor treatment based on the application of a low intensity direct electric current to the tumor tissue through two or more platinum electrodes placed within the tumor zone or in the surrounding areas. This treatment is noted for its great effectiveness, minimal invasiveness and local effect. Several studies have been conducted worldwide ...

Electrochemical processes have been extensively investigated for the removal of a range of organic and inorganic contaminants. The great majority of these studies were conducted using nitrate-, perchlorate-, sulfate-, and chloride-based electrolyte solutions. In actual treatment applications, organic and inorganic constituents may have substantial effects on the performance of electrochemical t...

in this investigation, attempts were directed to study the inhibitive effects of nitrite and phosphate base inhibitors for the carbon steel alloy samples, which are used in an acid gas treatment process (the sulfiran® solution), in fe-edta solution. electrochemical techniques, i.e. polarization curves and electrochemical impedance spectroscopy (eis), were used to evaluate the inhibition efficie...
