| 摘 要： | 通过间歇性实验对超声波协同纳米铁降解2,4-二氯苯酚进行了研究,结果表明:协同作用大大提高了降解率, 如在反应时间为2 h,纳米铁体系对2,4-二氯苯酚的降解率为11.3%,超声波体系对2,4-二氯苯酚的降解率为36%,两种反应体系的降解率迭加值为47.3%,而协同体系对2,4-二氯苯酚的降解率则达到88.3%.同时考察了时间、声强、pH、2,4-二氯苯酚初始浓度、反应器的直径和纳米铁粉的投加量等对协同反应降解效果的影响.

| Abstract: | The degradation of 2,4 - dichlorophenol by ultrasound cooperating nanoscale iron was studied through in-termittence experiments. The results show that the cooperation improved the degradation rale remarkable: the degradation with nanoscale iron alone is 11 .3% and ultrasound alone is 36% , it is 47.3% for the amount with two, however ,the degradation of ultrasound cooperating with nanoscale iron is 88.3% . At the same time, all kinds of effect factor e.g. : time, power intensity, pH, initialing concentration, the diameter of reactor and quantity of nanoscale iron was introduced. |

| Keywords: | nanoscale iron ultrasound cooperation 2 4 - dichlorophenol. |
