چکیده
T?xtile wastewater contains a variety of contaminants that are known to be hazardous. Synthetic dyes one the hazardous pollutants in textile industry resistant photo/bio d?gradation. They cannot d?stroyed under conventional treatment. This document presents review on electrochemical treatment wast?water containing synthetic organic by anodic oxidation for environmental protection. The mechanisms ?lectrochemical processes well explained. A larg? number electrodes have been tested this method. Therefore, pap?r aims summarize and discuss most important r?cent results available literature anode application r?moval dyestuffs. Finally, prospects process futur? research suggested.

Decolorization of synthetic textile wastewater using electrochemical cell divided by cellulosic separator
BACKGROUND Annually, large quantities of dyes are produced and consumed in different industries. The discharge of highly colored textile effluents to the aquatic environments causes serious health problems in living organisms. This paper investigates the performance of each of the electro-oxidation and electro-reduction pathways in the removal of reactive red 120 (RR120) from synthetic textile ...
متن کاملAn Electrochemical Investigation of Nano Cerium Oxide/Graphene as an Electrode Material for Supercapacitors
In this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. The electrochemical properties of the produced electrode are studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques in 3M NaCl, NaOH, and KOH electrolytes. Scanning electron microscopy (SEM) is used to characterize the mi...

متن کاملElectrochemical degradation of resorcinol using mixed oxide coated titanium electrode for wastewater treatment--A kinetic study
This study presents the theory and kinetics of electrochemical dlegradation of resorcinol in the presence of chloride using Tifl'i02 Ru02 Ir02 electrode. The rate constant is affected by chloride concentration, initial resorcinol concentration and current density. The rate of electrochemical oxidation is found to be a pseudo first order kinetic process. The maximum rate of reaction is obtained ...
