Efficiency of Electrocoagulation for Removal of Reactive Yellow 14 from Aqueous Environments

Background & Aims of the Study: Discharge of textile industry colored wastewaterwithout enough treatment into natural water resources cause serious pollution. Most of theconventional wastewater treatment methods are not effective enough to remove these dyesfrom wastewater. In this study, efficiency of electrocoagulation process with iron electrodesfor treatment of Reactive Yellow 14 dye from synthetic solution has been studied andconcluded.Materials & Methods: This experiment was conducted in a batch system with a volume of2 L that had been equipped with 4 iron electrodes. The effect of operating parameters, suchas voltage, time of reaction, initial dye concentration, and interelectrode distance on the dyeremoval efficiency was investigated.Results: In optimum condition (pH 2, voltage 40 V, electrolysis time 25 min, andinterelectrode distance 1 cm), electrocoagulation method was able to remove 99.27% ofReactive Yellow 14 from synthetic solution.Conclusions: Electrocoagulation process by iron electrode is an efficient method forremoval of reactive dyes from colored solution.
