摘要
包覆型纳米零价铁去除镍(II)离子和三氯乙烯(TCE)的结果表明:Ni2+和TCE的去除率均随着包覆型纳米零价铁的投加量增加而升高,随着溶液初始浓度的增加而降低。四种零价铁材料处理混合废水的能力依次为:NZVI 2+和TCE浓度都为5 mg/L,包覆型纳米零价铁的加入量为1.5 g/L,温度为30℃,反应时间为2.5 h,Starch-NZVI对Ni2+和TCE的处理效果最好,其中Ni2+的去除率为99.38%,TCE的脱氯率为49.36%。
Coated nano zero-valent iron removal of Nickel (II) ions and trichloroethylene (TCE) results showed that: The removal of nickel ions and TCE was better with higher dosage of nano zero-valent iron and lower initial concentration. Capacity of four kinds of zero-valent iron material handling wastewater was: NZVI + and TCE had best treatment effect, with Nickel (II) removal rate 99.38%, TCE degradation rate 49.36%.
