一种土壤重金属吸附剂及其制备方法
摘要：
本发明公开了一种土壤重金属吸附剂及其制备方法，所述土壤重金属吸附剂的密度小于1g/cm3，所述土壤重金属吸附剂包括质量比为1:1～100000:1的漂浮核以及杂化材料，其中，所述漂浮核的粒径为10μm～2000μm，密度小于0.5g/cm3；所述杂化材料包覆于所述漂浮核的外表面；所述杂化材料包括0.001wt％～20wt％的具有螯合基团的有机高分子以及99.999wt％～80wt％的纳米无机化合物。本发明还公开了该土壤重金属吸附剂的制备方法。本发明的重金属吸附剂由轻质漂浮核负载纳米无机化合物以及具有螯合基团的有机高分子而组成，易于分离回收及再生重复使用，具有良好的应用前景。
摘要（英）：

The invention discloses a soil heavy metal adsorbent and a preparation method thereof.The density of the soil heavy metal adsorbent is smaller than 1 g/cm<3>.The soil heavy metal adsorbent comprises a floating core and a hybrid material, wherein the mass ratio of the floating core to the hybrid material ranges from 1:1 to 100,000:1, the grain size of the floating core ranges from 10 micrometers to 2,000 micrometers, and the density of the floating core is smaller than 0.5 g/cm<3>; the outer surface of the floating core is covered with the hybrid material; the hybrid material comprises 0.001 wt%-20 wt% of an organic polymer with chelation groups and 80 wt%-99.999 wt% of a nanometer inorganic compound.The invention further discloses the preparation method of the soil heavy metal adsorbent.The heavy metal adsorbent is composed of the light floating core loaded nanometer inorganic compound and the organic polymer with the chelation groups, is easy to separate, absorb, regenerate and reuse, and has good application prospects.
