摘　　要：利用三氯化铁制备羟基铁交联剂,当pH值为5,FeCl3.6H2O固体投加量为10 mmol/g累托石,液固比为5∶1,反应时间为4 h,反应温度为60℃时,成功制备了改性累托石复合材料.利用制备的羟基铁交联累托石复合材料电化学处理含苯酚废水,结果表明:当电压为6 V,电解质NaCl浓度为0.1 mol/L,苯酚pH值为4,苯酚质量浓度为200 mg/L时,该复合材料能够很好地催化降解苯酚废水,其降解率可达到95%以上.Hydroxy-ferrum prepared by ferric chloride as the cross-linking agent,the modified rectorite composite was prepared successfully when the optimum reaction conditions were as follows: the pH 5,the addition of ferric chloride 10 mmol/grectorite,the liquid-solid ratio 5∶ 1,the reaction time 4 h,the temperature 60 ℃.Then the phenol wastewater was degradated by electrochemical method with modified rectorite composite.The results indicate that modified rectorite composite shows good function on the treatment of phenol waste water and the degradation rate reaches over 95% when voltage is 6 V,NaCl electrolyte solution is 0.1 mol/L,pH of phenol is 4,initial mass concentration of simulate phenol waste water is 200 mg/L.
