Zusammenfassung:The invention discloses a preparation method and application of a silver-containing composite adsorption membrane, which comprises the following steps: 1. dissolving polyethersulfone particles in N, N-dimethyl acetamide, adding silver nitrate, and stirring at 50 DEG C for 24 hours or more to form a uniform and stable membrane casting solution, and 2, casting a membrane casting solution on a cleanglass plate to form a membrane, soaking the membrane in a sodium chloride coagulating bath for 24 hours or more, carrying out solvent exchange, carrying out vacuum drying at 40 DEG C after the solventexchange is completed, and scraping the membrane with the thickness of 0.2 mm by using a scraper to obtain the silver-containing composite adsorption membrane. By preparing the composite membrane adsorbing material, material forming is achieved, so that the problems that a powdery adsorbing material is difficult to separate and regenerate in the using process are solved, the using efficiency is improved, the addition of s
