A micro-nano medical adsorbent resin powder material is a high-molecular polymer including carbon ions, hydrogen ions, and oxygen ions. The powder material includes a molecular structure includes a benzene ring and a hydroxyl group, and the polymer includes at least two or more molecules an overall particle size is in a range of 0.01-50 micrometer (um), preferably 0.01-1.5 micrometer (10-1500 nm).
