| 摘 要： | 本文考察了Fe3O4/纳米级Fe0对污染水中Cr(VI)的去除效果，以及Fe3O4投加量、腐殖酸投加量、温度对Fe3O4/纳米级Fe0去除水中Cr(VI)的影响。结果表明：Fe3O4/纳米级Fe0对水中Cr(VI)的去除效果很好，在2min时Cr(VI)的去除率就能够达到91.4%，这个值比纳米级Fe0单独作用120min时对 Cr(VI)的去除率还要高；Fe3O4与纳米级Fe0的配比为7.5:1时，Fe3O4/纳米级Fe0对Cr(VI)的去除效果最好。温度的升高加速了Fe3O4/纳米级Fe0对水中Cr(VI)还原降解反应的进行。

| Abstract: | The removal of Cr(VI) by Fe3O4/nanoscale Fe0 and the effect of Fe3O4 dosage, HA dosage and temperature on it were evaluated. The experiment results indicated that 91.4% Cr(VI) could be removed by Fe3O4/nanoscale Fe0 within 2 min compared with 5.1% by bare Fe3O4 and 79.0% by bare nanoscale Fe0. And the optimal ratio of Fe3O4 to nanoscale Fe0 mass lies at 7.5:1. High temperature could increase the Cr(VI) removal efficiency. |
