A magnetic solid polyamine adsorbent particle material having a surface coated with a polyamine group, having a particle diameter range of 0.5-500.0 µm, having a core-shell structure having a plurality of inorganic/organic shell layers, and a carbon-nitrogen bond-linked polyamine adsorption group for stabilizing the structure. The preparation method thereof mainly comprises the following basic steps: (1) preparing an inorganic substance coating layer; (2) surface double bond modification; (3) preparing an organic substance coating layer; and (4) preparing a magnetic solid polyamine adsorbent particle material. The adsorbent particle material can selectively chemically adsorb a heavy metal substance within a wide pH range, and can be recycled and reused. L'invention concerne un matériau de particule adsorbante de polyamine solide magnétique dont une surface est revêtue d'un groupe polyamine, présentant une plage de diamètre particulaire de 0,5 à 500,0 µm, ayant une structure à noyau-coque comportant une plural
