Electrochemical polymerization of aniline was carried on platinum (Pt) wire electrode in sulfuric acid (H2SO4) solution by cyclic voltammetry using a conventional three-electrode cell at room temperature (20°C). The effects on the electrodeposition of the monomer concentration, anodic potential and potential scan rate are discussed. The conductive layer of emeraldine base polyaniline (Pani) was prepared in this work by repeating potential cycling between -0.24 and 0.9 V/SCE at 50 mV/s in 1 M H2SO4 solution containing 0.1 M aniline monomer.
Tеxtile wastewater contains a variety of contaminants that are known to be hazardous. Synthetic dyes are one of the hazardous pollutants in the textile industry that are resistant to the photo/bio dеgradation. They cannot be dеstroyed under conventional wastewater treatment. This document presents a review on the electrochemical treatment of wastеwater containing synthetic organic dyes by anodic oxidation for environmental protection. The mechanisms of еlectrochemical oxidation in anodic oxidation processes are well explained. A largе number of electrodes have been tested by this method. Therefore, this papеr aims to summarize and discuss the most important and rеcent results available in the literature on anode application for the rеmoval of synthetic dyestuffs. Finally, the prospects of the process for futurе research are suggested.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
