On the Progress of Iron(Hydrogen) Oxide Adsorption of Phosphorus and Heavy Metals

文章简述了铁(氢)氧化物特性及其吸附机制,详细阐述了铁(氢)氧化物及其复合物吸附磷、重金属,重点综述了pH、磷及离子浓度、氧化、结晶尺寸、温度对铁(氢)氧化物及其复合物吸附污染物质的影响。

The absorption method is widely used in water treatment because of its simple operation,low cost and little pollution.Iron(hydrogen)oxides have not only large specific surface area but also hydroxyl functional groups in surface,which can effectively absorb phosphorus,heavy metals and other pollutants.This paper briefly describes the characteristics of iron(hydrogen)oxides and their adsorption mechanism.It introduces the adsorption of phosphorus and heavy metals by iron(hydrogen)oxides and their complexes in detail and reviews the effects of pH,phosphorus and ion concentration,oxidation,crystal size and temperature on the adsorption of iron(hydrogen)oxides and their complexes on pollutants.New complexes of iron(hydrogen)oxides and their adsorption properties should be further studied.It has a great application value to comprehensively analyze that iron(hydrogen)oxides can effectively absorb phosphorus and other pollutants.
