“…This process has been used for water softening using cation-exchange membrane and sodium chloride solution [179], the removal of potassium hydroxide from gold plating bath [180], the removal of hazardous metal ions, the pretreatment of ion chromatography in order to concentrate ions [181], and so on. There is a report on the utilization of pH difference as the driving force to transport ions through the cation-exchange membrane against the concentration gradient [182].…”

Membrane science is a relatively new area of applied chemistry and chemical engineering and plays a vital role in the field of alternative energy and separation applications. The field of membrane science is therefore an emerging area with enormous industrial and public health significance. Today, various kinds of separation membranes have been studied and utilized industrially in different processes including reverse osmosis, nanofiltration, ultrafiltration, microfiltration, electrodialysis, and pervaporation. Technical feasibility of all these processes largely depends on membrane and its properties. Among the separation membranes, ion exchange membranes are one of the advanced separation membranes. Therefore, this chapter addresses on different types of ion exchange membranes with reference to their preparation, properties, as well as their industrial applications. Although ion exchange membranes are broadly classified into homogeneous and heterogeneous membranes, this chapter also covers other types of ion exchange membranes such as amphoteric, mosaic, bipolar, interpolymer, and graft and block copolymer membranes. At the end, prospectives and conclusions on the ion exchange membranes have also been highlighted. The relevant literature was collected from different sources including Google sites, books, reviews, and research articles.

“…This process is easy to handle and only requires a few chemicals and low pumping energy. Donnan dialysis is widely used to recover or concentrate [ 20 , 21 , 22 ] and eliminate various ions such as nitrates [ 23 ], nitrates and nitrites simultaneously [ 24 ], fluorides [ 25 , 26 , 27 ], chromium [ 28 , 29 ], phosphates [ 30 ] and boron [ 18 , 19 ].…”

Response Surface Methodology for Boron Removal by Donnan Dialysis: Doehlert Experimental Design

The removal of boron by Donnan dialysis from aqueous solutions has been studied according to response surface methodology (RSM). First, a preliminary study was performed with two membranes (AFN and ACS) in order to determine the experimental field based on different parameters, such as the pH of the feed compartment, the concentration of counter-ions in the receiver compartment, and the concentration of boron in the feed compartment. The best removal rate of boron was 75% with the AFN membrane, but only 48% with the ACS membrane. Then, a full-factor design was developed to determine the influence of these parameters and their interactions on the removal of boron by Donnan dialysis. The pH of the feed compartment was found to be the most important parameter. The RSM was applied according to the Doehlert model to determine the optimum conditions ([B] = 66 mg/L, pH = 11.6 and [Cl–] = 0.5 mol/L) leading to 88.8% of boron removal with an AFN membrane. The use of the RSM can be considered a good solution to determine the optimum condition for 13.8% compared to the traditional “one-at-a-time” method.

“…The Donnan dialysis is a useful membrane process used to recover valuable ions and remove undesirable ones from some waste effluents [26][27][28][29][30][31][32][33][34]. The theory and principles behind the Donnan dialysis process are recently reviewed by Luo et al [35].…”

The removal of chromium (VI) from aqueous solutions by Donnan dialysis has been investigated in this paper. In this process, two anion-exchange membranes (AEMs) were used: Selemion ® AMV and Neosepta ® AFN. The amount of chromium (VI) removed was determined in terms of the following parameters: initial concentration of chromium (VI), type of anion-exchange membrane, concentration of counter-ion and magnetic stirring rate. A 24 full factorial design analysis was performed to screen the parameters affecting the Cr (VI) removal efficiency. Using the experimental results, a linear mathematical model representing the influence of the different parameters as well as their interactions was obtained. Analysis of the variance (ANOVA), the F-test and the student's test shows that the type of anion-exchange membrane is the most significant parameter affecting the chromium (VI) removal. The statistical analysis of the experimental data assumes it to be a normal distribution.
