Transport of Formic Acid Through Anion Exchange Membranes by Diffusion Dialysis and Electro‐Electro Dialysis

Competitive transport of hydrochloric acid and zinc chloride through polymeric anion‐exchange membrane

“…An extensive study on the recovery of formic acid from pickling solution in the leather industry using diffusion dialysis and electro-electro dialysis was a subject of the study. 5 Xu and Yang 6 carried out experiments focused on the simultaneous recovery of sulfuric acid and nickel from electrolysis spent liquor of relatively low acid concentration. The pilot experiments with surface crosslinked PPO anion-exchange membranes showed that nickel leakage can be controlled within 4%, and the acid recovery can attain as high as 66 -72%.…”

Continuous Separation of an H2SO4/CuSO4 Mixture by Diffusion Dialysis

“…Another experiment with surface cross-linked PPO anion-exchange membranes [7] used in the recovery of sulfuric acid and nickel from electrodialysis spent liquor showed that nickel leakage can be controlled within 4 % and the recovery of acid can reach 66-72 %. An extensive study on the recovery of formic acid from pickling solution in the leather industry using diffusion dialysis and electro-electrodialysis is described in [8]. Diffusion dialysis was used to recover H 2 SO 4 from waste sulfuric acid solutions in the diamond manufacturing process [9].…”

Transport properties of propionic acid in anion-exchange membrane Neosepta-AFN

“…To determine them, two types of equipment can be used: (i) a two-compartment dialysis cell with stirrers [1][2][3][4]; (ii) a continuous dialyzer (mostly with two compartments) [5][6][7][8]. In the former case, the experiments are carried out at unsteady state, when time dependences of the component concentration are recorded in both the compartments.…”
