摘要
采用微波辐射-NaHSO3还原法降解水中的2,4,5-三氯联苯(PCB29)。实验结果表明:相对于双模微波,单模微波可在较低功率和较短时间内辅助NaHSO3完成对PCB29的降解,PCB29被降解为联苯酚;在单模微波功率为200 W、NaHSO3加入量为30 g/L、反应时间为2 min的条件下,PCB29降解率为90%。
2,4,5-trichloro biphenyl （PCB29） in water was degraded by microwave radiation- NaHSO3 reduction process. The experimental results show that： PCB29 can be effectively degraded into diphenol xenol at lower power and shorter time by single-mode microwave in comparison with dual-mode microwave ; Under the conditions of microwave power 200 W, NaHSO3 dosage 30 g/L and reaction time 2 min, the degradation rate of PCB29 can reach 90%.
