摘　　要：本文针对实验室中产生的含铁废水,利用花卉植物瓜叶菊对Fe2+的富集特性予以净化,并研究了在净化过程中叶绿素含量、过氧化氢酶活性(CAT)和质膜透性的变化.结果表明,瓜叶菊对Fe2+具较强的富集与净化能力,随瓜叶菊对Fe2+富集量的增加,CAT活性下降,质膜透性增大.This paper studies the purification effenciency of Fe2+ in waste wa ter by Cineraria Cruenta and the variations of content of chlorophyll ,the activ e of CAT and cytomenbrane permeability in the course of purification.The results show that Cineraria Cruenta has great ability to purify Fe2+ in wastewater.The active of CAT is decent and cytomembrane permeability is raised in the process.
