| 摘 要： | 文章研究了Fe0的纯度、粒径和投加量以及酸洗预处理对水溶液中四氯化碳的还原性脱氯作用的影响,并对其脱氯的主要产物——氯仿进行了讨论。结果表明:(1)Fe0纯度越高,粒径越小,四氯化碳的去除效果越好;(2)在实验范围内,Fe0投加量越大,四氯化碳的去除效率越高;(3)酸洗后,四氯化碳的去除效果明显的提高;(4)Fe0纯度、粒径和投加量以及酸洗处理对四氯化碳的还原产物氯仿亦具有一定的影响,四氯化碳的去除与氯仿的产生之间存在着一定的对应关系。

| Abstract: | Influences of Fe0 purity,particle size,amount and acid-washing pretreatment on reductive dechlorination of CT in water solution as well as its main degradation product-chloroform were studied.Results indicated that better removal efficiency of CT was obtained with higher Fe0 purity and smaller Fe0 size.With more Fe0 amount was added,higher removal efficiency of CT was got.After acid-washing pretreatment,removal efficiency of CT was improved obviously.Fe0 purity, particle size,amount and acid-washing pretrea... |
