摘　　要：对氧氢氧化铁在水溶液中吸附重金属离子和光催化氧化降解有机污染物的发展和机理进行了总结,并对其在水处理和在环境矿物学中的应用和意义作了概括和探讨。用2种纳米氧氢氧化铁针铁矿(-αFeOOH),正方纤铁矿(-βFeOOH)处理偶氮染料分子甲基橙溶液,在自然光下,FeOOH/H2O2体系能使甲基橙溶液脱色率达90%,并且能将甲基橙分子中的苯环部分打开。This paper summarized the development and mechanism of iron oxyhydroxides＇ absorption of heavy metal ion and photocatalysis decoloration on organic contaminants.Iron oxyhydroxides＇ application and meaning to sewage disposal and environmental mineralogy were discussed in this paper.Disposal on methyl orange solution by two kinds of nanometer sized iron oxyhydroxides： α-FeOOH and β-FeOOH in visible light showed that methyl orange solution decolored by 90% by FeOOH/H2O2 system.And phenyl in methyl orange molecule was broken.
