以葡萄籽提取液绿色合成铁纳米颗粒（Fe-NPs）为催化剂，采用非均相类芬顿体系对间甲酚的降解进行研究。利用SEM、FT-IR和XRD等对合成的Fe-NPs进行表征分析。考察了溶液初始pH、催化剂质量浓度、H₂O₂用量和反应温度对降解的影响。结果表明，在溶液自然pH=6.51、催化剂质量浓度为0.30 g/L、30% H₂O₂用量为10 mL、反应温度为308.15 K条件下，100 mg/L间甲酚90 min时降解率达到95.75%。在最佳条件下，伪一级和伪二级动力学模型均能有效拟合Fe-NPs对间甲酚的降解过程，包括氧化降解和吸附。

Iron nanoparticles (Fe-NPs) are synthesized from grape seed extract,and used as heterogeneous catalyst for the degradation of m-cresol in a Fenton-like system.The properties of Fe-NPs before and after degradation are characterized by scanning electron microscopy (SEM),Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD),respectively.The effects of initial pH value,Fe-NPs dosage,hydrogen peroxide dosage and temperature on the degradation are investigated.The removal efficiency of 100 mg·L^-1 m-cresol can reach 95.75% in 90 min when the dosage of Fe-NPs is 0.30 g·L^-1,the dosage of 30 wt% H₂O₂ is 10 mL,pH=6.51 and the temperature is maintained at 308.15 K.Under the optimal conditions,both pseudo-first and pseudo-second order kinetic models can effectively fit the degradation process of m-cresol,including oxidative degradation and adsorption.
