摘要
海藻具有特殊的细胞壁结构,其化学改性后具有较高的重金属富集吸附能力。化学改性后的海藻具有吸附量大,吸附速率快以及简易的解吸附等优点,被认为是理想的生物吸附材料。本文描述了海藻吸附剂对重金属的吸附作用,分析了温度、pH值、光照对其吸附效率的影响并剖析了吸附机理,最后对海藻吸附剂在改性方面研究的进展情况和其未来的发展趋势进行了展望。
Algae has a special cell wall structure, which has higher enrichment ability to adsorb heavy metal after chemically modified. Algae has some advantages after chemically modified, including a large adsorbing capacity,fast adsorbing rate and easily desorbing etc.,which is considered an ideal biological adsorption materials. This paper describes the algae adsorption played parts on heavy metals by algae, analyses the temperature,p H,light on its adsorption effciency and analyses the mechanism of dsorption. Finally,its development of research on its modification in recent years,and it prospects the trend of the development of algae adsorbent as well.
