摘要	Laboratory study of recovering HNO(3) solution from acidic effluents discharged by an electrodialysis plant for extracting lithium from concentrated brine at East Taijinar Salt Lake, China, was conducted using diffusion dialysis (DD) with homogenous anion exchange membrane (DF120). The effects of concentrations of nitric acid and metal ions (including Li, Na, K, Mg, Ca) and water to spent acid flow rate (W/A) ratio on the performance of diffusion dialysis were investigated. Results indicated that acid recovery increased with the concentration of the feed. The membrane showed moderate monovalent permselectivity: divalent cations were more effectively retained as opposed to monovalent cations. The selectivity between metal and hydrogen ions were impaired by increasing W/A ratio. The acid recovery reached its maximum at 3.0 mol/L H(+), demonstrating that the efficiency at feeding concentrations above 3.0 mol/L would be low for the DF120 membrane. The increase of salt content in the spent acid to 3.0 mol/L and above conceivably impaired the selectivity of the membrane.
