“…It is a "clean" technology with no presence of the permanent residues for the separation of heavy metals (Issabayeva et al, 2006). Oztekin and Yazicigil (2006) found that electrodeposition is an applicable method for the recovery of metals under appropriate conditions. They investigated the electrolytic recovery of metals from aqueous solutions containing complexing chelating agents such as EDTA, nitrilotriacetic acid and citrate in a two-chamber cell separating with a commercial cationexchange membrane.…”

“…The AEMs (AHA, ACM, AMH) and CEMs (CMB, CMS, CMX) selected in this study were kindly supplied from Eurodia Co. These IEMs were prepared due to procedures in literature [19][20][21][22][23]. The experiments were carried out at the constant current by changing the cell voltage according to the variation of the current.…”

The recovery of bases from solutions containing salt forms of potassium was studied in cells separated by commercial ion exchange membranes. For this aim, two different types of techniques were applied. In the first technique, an equimolar quantity of acid solutions and different metallic salt solutions were used as an anolyte and a catholyte, respectively, in the cell separating with anion exchange membrane (AEM). In the second technique, an equimolar quantity of acid, base solutions, and different metallic salt solutions were used as an anolyte, a catholyte, and a solution in the middle chamber of the cell, respectively, in the cell separating with cation exchange membrane (CEM) and AEM. Effects of the current, the type of the membranes, the concentrations of the solutions, and the type of solutions on the recovery of bases were investigated and both of the techniques were compared. The results of the experiments were evaluated with the Statistical Package for Social Sciences program.

“…After t = 16 h, nickel ion was removed from SCEC at the linear rate of 7 (g.m -3 ).h -1 . During metal electrodeposition on the cathode, the involved mechanisms are diffusion, convection, and migration of metal ions and electrons toward the cathode surface, followed by electron adsorption to form adatom, and diffusion of the adatom to form crystal [10]. Without partition between the anode and the cathode chambers, hydrogen ions (H + ) that were formed in the anode were transferred onto cathode and formed H 2(g) that reduced the mass transfer toward the cathode surface.…”

“…Electrodeposition occurs based on the following reactions: Competing reactions sometime occur in the cathode, for instance hydrogen gas (H 2(g) ) formation and water hydrolysis. These reactions may influence nickel ion reduction on the cathode [10]. Membranes are sometimes used to separate the cathode and the anode, and optimize the reaction in each electrode.…”

PAPER • OPEN ACCESSRemoval of nickel ion from electroplating wastewater using double chamber electrodeposition cell (DCEC) reactor partitioned with water hyacinth (Eichhornia crassipes) leaves Abstract. Nickel is a heavy metal present in many types of industrial wastewater, and its contamination to the water bodies should be prevented. The objective of this research was to study the performance of Double Chamber Electrodeposition Cell (DCEC) for nickel ion removal. Water hyacinth (Eichhornia crassipes) leaves were used to separate the two chambers. The experiment was performed with synthetic electroplating wastewater in a batch system for 72 h. Changes of pH, electric current, and nickel ion concentration in the catholyte were monitored. An experiment with Single Chamber Electrodeposition Cell (SCEC) was also performed as comparison. After 72 h operation of DCEC, nickel ion concentration in the catholyte decreased from 2200 g.m -3 to 0.4 g.m -3 , equivalent to 99.98% removal. DCEC reactor performed better than the SCEC reactor that only achieved 59% removal. The results show that an almost-complete removal of nickel ion can be achieved with DCEC. Water hyacinth leaves can be used as low-cost alternatives for industrial membranes.
