| 摘 要： | 采用超声波／纳米铁粉协同脱氯降解四氯化碳，探讨了纳米Fe粉用量、反应液的初始pH值、CCl4初始浓度对脱氯降解效果的影响。结果表明：纳米铁粉用量为0．5g／100mL时，脱氯率最高；反应液的初始pH值为2．0时，可获得较高的脱氯率；CCl4的初始浓度越高，其脱氯率越低。

| Abstract: | A new method of the degradation of tetrachloride carbon by ultrasound synergized with nanoscale iron was studied. The factors affecting the reaction, such as the mass of nanoscale iron, initial pH and initial concentration of CCl4 were discussed. The results showed that the dechlorination efficiency was the highest when the mass of nanoscale iron was 0. 5 g/100 mL. The higher dechlorination efficiency was obtained when the initial pH was 2.0. The higher the initial concentration of CCl4, the lower the dechlorination efficiency. This work provided considerable experimental basis to the extension and application of this method and also developed a new approach to the dechlorination of organic chlorinated compounds. |
