题目：纳米氧化铁的制备及其对染料废水的去除性能研究

摘要：本文采用溶胶-凝胶法制备了纳米氧化铁，并对其进行了表征。结果表明，所制备的纳米氧化铁具有较高的比表面积和孔隙度，表面电荷密度较大，且颗粒分布均匀。进一步的实验表明，纳米氧化铁对染料废水具有较好的去除性能，去除率可达到80%以上。此外，研究还发现，纳米氧化铁对废水中的COD、BOD、NH3-N等污染物也具有一定的去除效果。

Abstract: In this paper, nano-sized iron oxide was prepared by sol-gel method and characterized. The results show that the prepared nano iron oxide has high specific surface area and porosity, high surface charge density, and uniform particle distribution. Further experiments show that nano iron oxide has good removal performance for dye wastewater, with a removal rate of over 80%. In addition, the study also found that nano iron oxide has a certain removal effect on pollutants such as COD, BOD, and NH3-N in wastewater.
