Electrodialysis as a potential technology for 4-nitrophenol abatement from wastewater

Abstract

4-Nitrophenol is a widely used emerging pollutant in various industries, including the production of agrochemicals, drugs, and synthetic dyes. Due to its potential environmental harmful effects, there is a need to study its reuse and removal from wastewater. This study used electrodialysis technology to separate 4-nitrophenol ions using a four-compartment stack. The effects of supporting electrolyte concentration, pH, voltages, and current density on the performance of electrodialysis for separating 4-nitrophenol were investigated. A high extraction percentage of 77% was achieved with low energy consumption (107 kWh kg-1) when high 4-nitrophenol flows and transport numbers were reached.

Keywords: 4-Nitrophenol recovery; 4-Nitrophenol removal; Electrodialysis; Emerging concern contaminants; Emerging technologies; Environmental remediation.
