摘要:
应用改进液相还原法合成纳米Pd/Fe双金属颗粒并对2,4-二氯酚进行还原脱氯,探讨双金属颗粒的钯负载率和初始pH值对脱氯效率的影响.结果表明,合成的纳米钯/铁颗粒分散均匀,平均粒径为50 nm.纳米Pd/Fe双金属颗粒对2,4-二氯酚的脱氯反应符合拟一级反应动力学方程.量子化学计算与还原脱氯实验均表明,分子中氯原子的化学环境对还原脱氯过程具有明显影响.
Abstract:
Nanoscale Pd /Fe bimetallic particles were prepared by a modified liquid reduction method and were applied to degradate 2,4 -dichlorophenol. Some factors,such as Pd /Fe ratio and initial pH,were studied in the course of 2,4 -dichlorophenol degradation. The results showed that particles with small size were dispersed more evenly and the average diameter was 50 nm. The degradation of 2,4 -dichlorophenol followed the pseudo-first-order reaction kinetics. The results of quantum-chemistry computation and the experiments indicated that the chemical environment of the chlorine atoms had significant influence in the process of degradating 2,4 -dichlorophenol.
