“…The membrane resistance and the resistance of ionic transfer through the interface (i.e. the diffusion boundary layer and the electrical double layer) of the different commercial IEMs could be distinguished by the analysis of EIS under the condition of various salt concentration, liquid flow rate and temperature [16,18]. Especially, the EIS study of the IEM system performed by Park et al [19,20] provided an approach of investigating the BSA fouling phenomena on the AEM and helped to get a better insight into the changes of the interfacial layers between the AEM and solution.…”

In this study, the fouling of anion exchange membrane (AEM) in electrodialysis was investigated using sodium dodecyl sulfate (SDS) as a model foulant, and the effect of membrane cleaning on the properties of the fouled AEMs was examined further. Results showed that the severer fouling of AEM was caused by the higher concentration of SDS in the feed solution, and a dense SDS fouling layer was formed on the AEM surface, causing the obvious increase of electrical resistance and the deterioration of desalination performance. Electrochemical impedance spectroscopy (EIS) indicated the SDS fouling layer on the AEM could hinder, even restrict completely the transmembrane migration of the ions, especially at high concentration of SDS. The cleaning experiment showed the cleaning effect of ultra-pure water was similar to that of HCl solution, but was better than that of NaOH solution, in which most SDS on the fouled AEM could be removed effectively by cleaned in ultra-pure water. EIS of the fouled AEMs before and after cleaned indicated that the remaining SDS on the cleaned AEM had almost no influence on the transmembrane migration of the ions through AEM.

“…Estimating the Melt Structures In an aqueous solution system at room temperature, R ct can be expressed by Eq. (9), 34) where C s is the electrolyte concentration and γ is a coefficient. The parameter corresponding to electrolyte concentration in the present study is considered to be the concentration of an alkaline earth metal oxide that can move relatively freely in the melt.…”

“…By performing a fitting to an equivalent circuit, using complex nonlinear least-squares enables to interpret the experimental impedance data [37]. By this method, the geometrical capacitance of the film can usually be neglected but it requires an evaluation of the surface morphology of the IEM and the thickness of the diffusion double layer for the capacitance to be used [38].…”

The use of ionizing radiation processing technologies has proven to be one of the most versatile ways to prepare a wide range of membranes with specific tailored functionalities, thus enabling them to be used in a variety of industrial, environmental, and biological applications. The general principle of this clean and environmental friendly technique is the use of various types of commercially available high-energy radiation sources, like 60Co, X-ray, and electron beam to initiate energy-controlled processes of free-radical polymerization or copolymerization, leading to the production of functionalized, flexible, structured membranes or to the incorporation of functional groups within a matrix composed by a low-cost polymer film. The present manuscript describes the state of the art of using ionizing radiation for the preparation and functionalization of polymer-based membranes for biomedical and environmental applications.
