“…Membrane technology has rapid development recently primarily due to its advantages and potential to various applications in various sectors [63][64][65][66][67]. Besides providing selective layer to one of reaction component, the membrane can also play a role as catalyst support even active catalytically itself.…”

Solvent extraction separation of nickel and cobalt from a sulfate solution containing iron(II) and magnesium using versatic 10 AIP Conference Proceedings 1805, 030003 (2017) Abstract. Wastewaters from electroplating industries are usually contaminated with nickel up to 1000 mg/L. According to environmental regulations worldwide, nickel concentration on wastewaters must be controlled to an acceptable level before being discharged to the environment. This paper offers an alternative way to develop an efficient effluent-free technology to reduce the nickel content of rinse water so that the treated water could be recycled for rinsing and subsequently to workout methodology to recover nickel by electrodeionization (EDI). Electrical voltage and initial nickel concentration were varied to study the effect of the parameters. Results showed that EDI could remove nickel effectively which gives an outstanding result in terms of product quality. Nickel concentration on diluate chamber decreased up to 99% after 60 and 180 minutes for nickel concentration of 300 and 1000 mg/L, respectively. Meanwhile, the increase of electrical voltage led to faster nickel removal.

“…Ion-exchange membrane (IEM) is a charged membrane which is mainly used as a selective separator for ionic components. IEM has been widely used in a number of different processes and in the various field of applications such as desalination and seawater pre-concentration, production of chlorine-alkaline, production of organic acids and organic salts, production of ultrapure water, wastewater treatment, and energy generation [16][17][18][19][20][21][22][23]. With those various potential applications, IEM-based processes are considered to be the crucial processes in water and energy supply, chemical industry, and environmental protection.…”

Abstract. Extensive application of synthetic ion-exchange membrane (IEM) in many areas has necessitated the improvement of their properties. Recently, the introduction of nanoparticles into polymeric membrane has attracted growing interest since the combination of both materials results in better properties. This well-known mixed-matrix membrane exhibits superior characteristics compared to an individual polymeric membrane. Properties of the nanoparticles such as electrical conductivity, hydrophilicity, and adsorption capacity can be utilized to produce the IEM with better physicochemical, electrochemical, and mechanical characteristics. The nanoparticles may also be used to achieve a specific characteristic such as an antibacterial property and monovalent ion permselectivity. In this paper, preparation, the role of inorganic materials and performance of mixed-matrix IEM are reviewed. In addition, challenges facing mixed-matrix IEM and strategies taken to overcome those challenges and future perspectives are discussed.
