  ABSTRACT: The discharge of dye wastewater poses a serious threat to the environment and human health. Membrane separation technology based on electrostatic adsorption is considered an effective method for dye removal. However, its long-term application is hindered by the saturation of adsorption sites. In this study, an anionic dye-adsorbing membrane was fabricated via a codeposition strategy, combined with patterned silver gel to impart conductivity. Acting as a cathode, the membrane electrolyzes water to generate OH? ions at the interface that deprotonate the functional groups, thereby releasing the adsorbed dyes in situ. The membrane exhibits excellent dye rejection performance and enables sustainable separation over multiple cycles under this electro-assisted cleaning. This strategy avoids the use of additional reagents or secondary chemical pollutants, offering an efficient and sustainable membrane separation solution for the treatment of dye-containing wastewater.
