中文摘要：

水合氧化铁是一种优良的吸附剂,对多种污染物质都有吸附作用。吸附机理主要是靠水合氧化铁和被吸附的物质形成配位络合物或静电吸引作用进行吸附。pH、离子强度、有机物及其制备工艺都会影响水合氧化铁的吸附性能。现在60℃环境条件下制备水合氧化铁并负载到颗粒活性炭上,吸附容量达到了26 mg.g-1。最后提出了从制备工艺方法改进和降低水合氧化铁的纳米粒径上来进一步提高水合氧化铁的吸附性能。

英文摘要：

Hydrous ferric oxide（HFO） is a kind of fine adsorbent,which can adsorb many pollutants.The mechanism of adsorption is that HFO can form the surface complexation or has electrostatic attraction with pollutants.pH value,ionic strength,organic matter and the process of preparation can effect the adsorption of HFO.the adsorption capacity of HFO preloading on granular activated carbon is 26 mg·g-1.At last,the improvement of the preparation of HFO and the decrease of nanometer particle size to enhance the adsorption capacity of HFO is put forward.
