| 摘 要：用硼氫化鈉還原氯化鐵溶液合成了氧化鐵納米顆粒（IONPs），紫外條件下，IONPs降解合成石油廢水，經(jīng)化學(xué)需氧量（COD）測定法評價(jià)降解量。結果表明，IONPs/UV對合成石油廢水COD的去除效果優(yōu)于紫外線(xiàn)光單獨處理。pH為8的UV光和0.8 g IONPs的組合可以使COD去除率達95.5%。IONPs/UV降解合成石油廢水的速度比純紫外光快1.3~2.0倍。IONPs/UV對合成石油廢水COD的去除符合準一級動(dòng)力學(xué)模型，速率常數k在0.013 3~0.026 9 min−1范圍。 |

| Abstract：Iron oxide nanoparticles (IONPs) were synthesized by reducing ferric chloride solution with sodium borohydride. The IONPs and UV light were used to degrade synthetic petroleum wastewater. The degradation amount was evaluated by chemical oxygen demand (COD) measurement. The results showed that IONPs/UV had better removal effect on COD of synthetic petroleum wastewater than UV alone. The combination of UV light at pH 8 and IONPs at 0.8 g could achieve a COD removal rate of 95.5%. The IONPs/UV degradation rate of synthetic petroleum wastewater was 1.3~2.0 times faster than that of pure UV light. The removal of COD from synthetic petroleum wastewater by IONPs/UV accords with the quasi-first-order kinetic model, with a rate constant k ranging from 0.013 3 to 0.026 9 min−1. |
