摘要
利用自制的二氧化硅包覆型纳米零价铁在常温中性条件下还原降解了2,4,6-TCP,简要探讨了包覆型纳米零价铁的投加量和2,4,6-TCP初始浓度对降解效率的影响,并对其反应动力学进行了简要说明。降解反应过程符合一级反应动力学,表观反应速率常数Kobs=0.011 13 h-1。
Abstract： The home-made silica coated nanometer zero-valent iron（NZVI） has been used for reducing and degrading2,4,6-TCP at room temperature under neutrality condition. The effects of the dosage of coated nano-scale zero-va-lent iron and the initial concentration of 2,4,6-TCP on degrading efficiency are discussed briefly. Its reaction kinet-ics is explained briefly. The process of reaction degradation accords with the first grade reaction kinetics. The speedconstant of apparent reaction Koobs = 0.011 13 h-1.
