▎ 摘　　要

NOVELTY - A porous separation membrane with adsorption performance comprises a polymer layer and an optional support layer. The surface and the interior of the polymer layer are three-dimensional fiber structures formed by interweaving polymer fibers and forms three-dimensional interconnected network pore structures that penetrate each other, and an adsorbent is uniformly dispersed in the polymer layer. USE - Porous separation membrane with adsorption performance used in water pollution monitoring, liquid filtration, adsorption materials and water purification (all claimed). ADVANTAGE - The membrane reduces the use cost of the adsorbent, solves the problem that secondary pollution is easily caused by easy agglomeration in the adsorption process, and improves the adsorption performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the porous separation membrane, which involves carrying out atomization pretreatment of the polymer membrane casting solution containing the adsorbent by combining a non-solvent induced phase separation method.
