Removal of manganese (II) from aqueous solution by ionic liquid impregnated polymeric sorbent and electrodeionization (EDI) techniques

Feasibility of electrodeionization for phosphate removal

“…Thus, the results revealed that reducing the flow rate of the solution from 2 to 1 L/h reduced the phosphate removal rate by 2%. This finding is in line with that of past studies that showed that increasing the flow rate of the solution improves the ion removal rate by increasing mass transfer and decreasing film thickness on the surface of the resin (Sarıçiçek et al, 2021;Soysüren et al, 2022;Zahakifar et al, 2020).…”

“…The solutions in the EDI cell were circulated by using magnetic pumps. Specifically, the MD 15R (Ölçü kontrol, Türkiye) magnetic pump was utilized for the anode and cathode compartments, whereas the MD20 (Ölçü kontrol, Türkiye) magnetic pump was employed for the dilution compartment (Sarıçiçek et al, 2021; Soysüren et al, 2022).…”

Polymer-enhanced ultrafiltration–electrodeionization hybrid system for the removal of boron

“…20 As the flow rate increases, the layer thickness on the resin surface decreases, accelerating the ion transfer and increasing the removal rate. 19,43,44 Furthermore, increasing the flow rate of the feed solution increases the number of feed water circulation cycles, which can result in a higher removal rate.

Adsorption removal of Mn2+ and NH4+–N from electrolytic manganese metal wastewater by modified phosphate ore flotation tailings

“…Mn 2+ and NH 4 + -N can be removed by catalytic oxidation, chemical oxidation, physicochemical adsorption, breaking point chlorination, membrane treatment, biophysical methods, electrochemical, chemical precipitation and stripping methods. [9][10][11][12][13][14][15][16][17][18][19] In industrial production, Mn 2+ Mn 2+ and NH 4 + -N were main removed in the form of solidified precipitates and converted to ammonia gas, respectively. The above methods can remove high concentrations of Mn 2+ and NH 4 + -N, but low concentrations of Mn 2+ and NH 4 + -N also remain in the EMMW.…”
