The invention relates to a magnetic solid organic sulfur adsorbent granular material containing an organic sulfur adsorption group, and the organic sulfur adsorption group can be a mercapto, thioether, or dithiocarbamic acid group. In a wide pH value scope, especially under the acidic condition, the magnetic solid organic sulfur adsorbent granular material has selective adsorption effect on heavy metal and precious metal in a solid-liquid suspension (mixing ) system such as water body and soil, can be easily separated from water or soil or the solid-liquid suspension system by a magnet or a magnetic separation device, has the advantages of convenient regeneration, low cost, realization of automatic large-scale metal ion separation through being used in a fluid bed or an ore dressing apparatus, and is suitable for being used in the industries of environmental protection, sewage treatment, biologic separation and oil dressing. 本发明涉及含有机硫吸附基团的磁性固体有机硫吸附剂颗粒材料，有机硫吸附基团可以为巯基、硫醚基团、氨荒酸基团等。该磁性固体有机硫吸附剂颗粒材料可在宽pH值范围内，特别是酸性条
