Efficiency of Electrocoagulation for Removal of Reactive Yellow 14 from Aqueous Environments
Journal Title: Archives of Hygiene Sciences - Year 2013, Vol 2, Issue 1
Abstract
Background & Aims of the Study: Discharge of textile industry colored wastewater without enough treatment into natural water resources cause serious pollution. Most of the conventional wastewater treatment methods are not effective enough to remove these dyes from wastewater. In this study, efficiency of electrocoagulation process with iron electrodes for treatment of Reactive Yellow 14 dye from synthetic solution has been studied and concluded. Materials & Methods: This experiment was conducted in a batch system with a volume of 2 L that had been equipped with 4 iron electrodes. The effect of operating parameters, such as voltage, time of reaction, initial dye concentration, and interelectrode distance on the dye removal efficiency was investigated. Results: In optimum condition (pH 2, voltage 40 V, electrolysis time 25 min, and interelectrode distance 1 cm), electrocoagulation method was able to remove 99.27% of Reactive Yellow 14 from synthetic solution. Conclusions: Electrocoagulation process by iron electrode is an efficient method for removal of reactive dyes from colored solution.
