“…Moreover, the effect of pH value increases is the deposition of a metal ions in the membrane surface that cause the losses of membrane performance called membrane fouling [10,11]. When the electrodialysis process was conducted with electric voltage over the limiting current, the decrease of current efficiency indicates that the electric current is used for other processes, such as water splitting, back diffusion of ion from concentrated to diluate compartment, and co-ion transfer [19].…”

“…The advantages of electrodialysis compared to other methods are the less use of chemicals and ability to separate compounds in small concentrations and low use of energy [11,16]. Studies to recover lithium using electrodialysis have been conducted by several researchers, which typically used standard ion exchange membranes or liquid ion exchange membranes [9,17,18,19].…”

Electrodialysis is a separation process which ions are transported through semi permeable membranes under an influence of electric potential. In this research, electrodialysis using monovalent ion exchange membranes was applied to separate lithium ions from mixtures of lithium-cobalt aqueous solution. The study aims to examine factors that affect the performances of electrodialysis monovalent membrane, such as applied voltage, flow rate, and the concentration of cobalt as co-ion. The research was conducted using electrodialysis PC cell BED 64004, monovalent cation exchange membrane (PC-MVK) and monovalent anion exchange membrane (PC-MVA) produced by PCA-PolymerchemicAltmeier, GmbH, Heusweiler, Germany. The effect of applied voltage was studied by varying the voltage in the range of 1-4 volt/cell volt. The effects of flow rate and initial concentration of ion were studied by changing the flow rate (10, 15, and 20 L/h) and varying the ratio of initial concentration between Li and Co ions (100-100, 100-400, and 100-500 mg/L). The results exhibited that the highest separation capacity of lithium (99.40%) was obtained when using the optimum applied voltage of 1 volt/cell. Low energy consumption would be obtained when using a low voltage for the process separation. The optimum flow rate for the lithium separation using electrodialysis monovalent membrane in this research was 15 L/h. The greater flow rate reduced the current efficiency and increased the energy consumption. When the concentrations of cobalt were increased in the range of 100-500 mg/L, the results indicated a decrease of current efficiency but an increase of energy consumption showing the influence of concentration of cobalt to transportation of lithium ions and selectivity of monovalent membrane.

“…These membranes partition electrolyte into segments [15,21]. By applying an electrical potential to the cell, charged particles (negative or positive) in the electrolyte move towards the electrodes with the opposite charge, consequently, ionic concentration will increase in some compartment and deplete in the adjacent ones [12,21,23].…”

“…ED has been successfully applied for different purposes such as: removal of hardness [12][13][14], separation of ionic species [21,24], recovery of beneficial products (e.g. PO4-P and NH4-N) from effluents [8,9,22,23,25] and desalination [9,15,26,27]. ED can also be implemented for the treatment of industrial wastewater [17,28] such as reducing electrical conductivity from almond industry [29], chloride removal from wet flue gas desulfurization wastewater [28], or removal of harmful ions such as F -, NO3 -, CLand Brand heavy metals such as pb 2+ , Ni 2+ , Cu 2+ , Cr 3+ , Mn 2+ , Fe 3+ , etc.…”

The presented paper describes an experimental study to reduce electrical conductivity (EC) of composting leachate-polluted water by using electrodialysis (ED) process. High efficiency, simple operation, low waste generation and selectivity are considered as major advantageous of applying ED process. Along with evaluation of ED method for desalination, the possibility of the process for COD (chemical oxygen demand) removal was also studied. The impact of- applied voltage, feed concentration and process time on ED performances were investigated. Increasing of the applied voltage and decrease of feed concentration enhanced the reduction of EC and improved the COD removal from the sample. At optimal condition (Voltage=10 Volt, feed solution=Cf/4 and time operation=120 min), the reduction of EC and COD removal were 92.7%, and 83.8%, respectively. Applying higher voltage and using more feed solution concentrations resulted in more energy consumption. The obtained results showed that ED method can be considered as an acceptable method to reduce salt and organic content.

Recent Advances in the Lithium Recovery from Water Resources: From Passive to Electrochemical Methods

et al. 2022

The ever-increasing amount of batteries used in today's society has led to an increase in the demand of lithium in the last few decades. While mining resources of this element have been steadily exploited and are rapidly depleting, water resources constitute an interesting reservoir just out of reach of current technologies. Several techniques are being explored and novel materials engineered. While evaporation is very time-consuming and has large footprints, ion sieves and supramolecular systems can be suitably tailored and even integrated into membrane and electrochemical techniques. This review gives a comprehensive overview of the available solutions to recover lithium from water resources both by passive and electrically enhanced techniques. Accordingly, this work aims to provide in a single document a rational comparison of outstanding strategies to remove lithium from aqueous sources. To this end, practical figures of merit of both main groups of techniques are provided. An absence of a common experimental protocol and the resulting variability of data and experimental methods are identified. The need for a shared methodology and a common agreement to report performance metrics are underlined.
