Use of electrodialysis to remove silver ions frommodel solutions and wastewater

San copolymer membranes with ion exchangers for Cu(II) removal from synthetic wastewater by electrodialysis

“…These results are in good agreement with the ones reported in literature (Güvenç and Karabacakolu, 2005;Kabay et al, 2002).…”

Sorption of silver ion from aqueous solutions using conducting electroactive polymers

“…Different treatment techniques (adsorption, extraction, ionexchange resins, reverse osmosis, metal replacement, precipitation, electrolysis and electrodialysis) have been developed for removal of silver ions from wastewaters [6][7][8][9][10][11][12][13][14]. Thus, there is a need for introducing an efficient method for the removal or recovery of silver ion from waste solutions generated from the mentioned industries due to the both economical and environmental points of view.…”

The treatment of cyanide from gold mine effluent by a novel five-compartment electrodialysis

“…(8). In comparison to the energy consumptions of traditional three-compartment ED, the value of 4.66 kWhm À3 (or 4.10 kWhm À3 ) at 14 V was close to that of 4.73 kWhm À3 (or 3.96 kWhm À3 ) at 15 V [46], and the value of 16.58 kWhm À3 at 30 V was lower than that of 17.88 kWhm À3 25 V in our previous work [28]. In the view of removal rate, energy consumption and current efficiency, 30 V was adopted as the optimal applied voltage for ED process in gold mine effluent treatment with heterogeneous or homogeneous ion exchange membranes.…”

“…The energy consumption (E, kwh/m 3 ) (not including the energy consumption used in driving solution circulation in the different compartments) can be defined by Eq. (8) [31,46]:…”

“…The reason can be attributed to the migration of H + from AEC to ACC towards the cathode. The dissociation of water was realized at the anode and given by the following reaction [46,54]:…”
