生物法合成纳米铁的研究进展

纳米铁颗粒的制备技术发展迅速,方法多种多样。生物法因其具有原料来源广,反应条件温和,产物纳米级颗粒不易团聚,以及有毒副产物少等特点,成为学者们争相研究的对象。对近几年国内外采用微生物、植物提取物等合成纳米铁材料的方法及机理进行了阐述,综述了纳米铁在环保领域的应用,并对今后深入研究生物法合成纳米铁的前景进行了展望。

RESEARCH PROGRESS ON BIOSYNTHESIS OF IRON NANOPARTICLES

With various preparing methods emerged，there has been a fast development in nanoparticals preparing techniques． Biological method become a popularized object to research by scholars because of many advantages of biosynthetic nanoparticles such as a wide source of raw materials，mild reaction conditions，nonagglomerated nanoparticles，and less toxic byproducts． The synthesis methods and mechanism of iron nanoparticals by using microorganism and plant extracts at domestic and abroad are expounded，and application of iron nanoparticles in the field of environmental protection were reviewed． Finally，the indepth study on synthesis method of iron nanopaticals in the future was prospected．
