摘要
采用较简单的方法合成了光催化活性较低、吸附性能较好的纳米Fe2O3,研究其对Cr(Ⅵ)的吸附行为并进行了相应的比较,结果表明,纳米金属氧化物Fe2O3对Cr(Ⅵ)的吸附酸度较宽,吸附效率较高,吸附时间短,吸附Cr(Ⅵ)后的纳米金属物用2.0mol/NaOH洗脱处理后均可重复使用,应用于环境水样中Cr(Ⅵ)的处理,效果很好。
Fe-2O-3 synthesized by a simple method with relative low photocatalytic activity and good absorbing capability was studied to assess its absorbing of Cr (VI). Results showed that Nano-Fe-2O-3 is efficient to treat Cr (VI) in aqueous samples, with wide absorption acidity, high absorption efficiency and short absorption time.
