活性炭纤维-微波辐射去除水中三氯生效果的实验研究

REMOVAL OF TCS FROM AQUEOUS WATER BY AFC-MICROWAVE RADIATION

采用活性炭纤维-微波(ACF-MW)辐射对水中三氯生(TCS)的去除进行研究,考察了活性炭纤维(ACF)投加量、微波功率、p H、TCS初始含量、阴离子表面活性剂十二烷基苯磺酸钠(SDBS)等因素对TCS去除效果的影响。结果表明,ACF-微波辐射联用可以有效地去除TCS,当微功率为300 W,活性炭投加量20 mg/L时,20 min后TCS去除率可达91%;实验范围内,TCS去除随ACF投加量的增大而增大,ACF投加量从5 mg/L增加到100 mg/L,TCS的去除率从24.9%上升到96.3%;TCS去除率随微波功率的增强加而增加,微波功率从100 W增加到500 W时,TCS去除率由56.1%提高到76.7%;碱性环境会抑制ACF对TCS的去除;SDBS对TCS的去除影响不显著。

Activated carbon fiber （ACF）-Microwave radiation was used to remove ticlosan （TCS） exist in water. The factors such as ACF dosage, microwave radiant intensity, initial concentration of TCS and sodium dodecylbenzenesulfonate （SDBS） on TCS removal were investigated. The results showed that TCS could be removed effectively by ACF-Microwave radiation. When the MI power was 300 W and dose of ACF was 20 mg/L the removal rate could reach 91% in 20 min. Under given condition, the removal rate of TCS increased from 24.9% to 96.3% when the dosage of ACF from 5 mg/L to 100 mg/L. With the increasing of MI power from 100W to 500 W, the removal rate increased from 56.1% to 76.7%. TCS removal was inhibited by alkaline .TCS adsorption was not significantly affected by the SDBS dosage.
