Diffusion dialysis (DD) with anion exchange membranes (AEMs) as the core component is an ideal technology for acid recovery from acidic wastewater. Herein, a series of TEA–BPPO AEMs were prepared from triethanolamine (TEA) and brominated polyphenylene ether (BPPO) using the solution casting method. The structures of the prepared membranes were characterized and analyzed through nuclear magnetic resonance hydrogen spectroscopy ( 1 H NMR), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) spectroscopy, and scanning electr...
