“…These runs showed significant 4-NP separation and an accurate mass balance. The results suggest that the 4-nitrophenol ion is not degraded or adsorbed by the AEM (Fehér et al 2020). The 4-NP separation values achieved in the CC after 360 min in the 6_70_500 and 10_70_500 runs resulted in 38.5 and 40.0 ppm, respectively.…”

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. In this study, electrodialysis technology was used 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 4nitrophenol 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.

“…Moreover, a lot of wastewater will be generated to recover the ionic resins. Electrodialysis [22] is a method to separate substances in solution by migrating ions under an electric field. An electric field is generated by an externally connected DC power supply, which promotes the anions in the desalination compartment to enter the concentrate compartment through an anion exchange membrane.…”

Electroreduction of oxalic acid (OA) is an effective process to produce glyoxylic acid (GA). However, electrochemically generated GA solution is yellow, which lowers the quality of GA and affects the application in producing the downstream products. It is urgent to investigate the composition of chromogenic substances (CSs) and separate them from the GA solution. In this work, the presence of tartaric acid, glyceric acid, and pyruvic acid in the electrochemically generated GA solution is successfully confirmed by high‐performance liquid chromatography‐electrospray‐mass spectrometry. Tartaric acid is originally generated from GA and glycolic acid, and then further reduced to obtain chromogenic glyceric acid and pyruvic acid. 92.97 % of CSs could be successfully removed from the GA solution by electrodialysis at 240.64 A/m2 and 25 °C. A separation of OA and GA is also achieved by electrodialysis. This study makes a significant contribution to the industrialization of electroreduction process to prepare GA.

A comprehensive mathematical model is proposed to study the transport phenomena in an electrodialysis (ED) process employed to recover lithium hydroxide and sulfuric acid from the lithium sulphate solution derived from a recycling process of spent lithium-ion battery material. The model is developed based on the conservation equations of mass and ions, and considers electrolyte solutions consisting of mono- and multivalence ions. The concentration polarization at ion exchange membranes (IEMs) and their adjacent diffusion boundary layers as a function of the applied current, inlet concentrations, and flow rate are computed. Experimental data from a three-compartment ED cell are used for validation. A parametric study is performed to evaluate the impact of parameters on transmembrane fluxes of ion and water. It is revealed that increasing current leads to enhancement of the transmembrane water and concentration polarization across IEMs. Feeding solutions consisting of smaller ions result in lower water transfer through IEMs. Raising the lithium concentration at the dilute channel increases the LiOH concentration due to reduced transmembrane water transfer. Using the uncertainty propagation method, it is found that current and counter-ion radius are the most influential parameters affecting the outlet concentration of concentrate channel and transmembrane water transfer.
