| 摘 要： | 天然吸附剂由于其本身结构的特殊性,对重金属离子有一定的吸附效果,但是原始的吸附剂在工程处理应用中有一定的局限性,如耐酸碱性不高、吸附量不大等,因此在实际应用中采用较多的典型吸附剂多为改性材料,改性后的吸附剂提高了对环境的耐受性和对金属离子的吸附量,对于去除和回收水体中重金属有很大的优势和发展前景。

| Abstract: | With the special structure,natural sorbents can adsorb heavy metal ions in some way.However,it＇s limited to use primary sorbents for projects due to their disadvantages such as low alkalinity or acidity and limited sorption capacity.Mostly modified sorbents are used due to their improved environmental tolerance and sorption capacity,which have many advantages in removal and recovery of heavy metals in water and have bright prospect in future. |

| Keywords: | Natural adsorbents modified heavy metal adsorption properties |
