摘    要:以江水-狗牙根构成的有机体系为研究对象,通过动态模拟试验,研究了Cr(Ⅵ)在狗牙根中的富集迁移情况。研究表明,狗牙根在Cr(Ⅵ)初始浓度在5.0mg/L及以下能比较正常地生长发育,Cr(Ⅵ)初始浓度达到10.0mg/L明显中毒,生长发育很缓慢。随着处理的Cr(Ⅵ)质量浓度的增加富集迁移量逐渐增大,且能明显降低江水中的Cr(Ⅵ)浓度。

关 键 词:Cr(Ⅵ)  狗牙根  离子迁移  模拟研究

Abstract:Taking the water of Changjiang River and the organic composition of Cynodon dactylon system as the research object,the enrichment migration situations of Cr (Ⅵ) in Cynodon dactylon were studied by dynamic simulation test. The studies showed that Cynodon dactylon can grow and develop at the initial concentration of Cr (Ⅵ) was 5. 0 mg / L and below. When the initial concentration of Cr (Ⅵ) reach 10. 0 mg / L,apparent poisoning was shown in Cynodon dactylon and it grew slowly. With the increasing of Cr (Ⅵ) mass concentration gradually,the amount of migration increased gradually. And the concentration of Cr (Ⅵ) in river was obviously reduced.
Keywords:Cr(Ⅵ)  Cynodon dactylon  Ion mobility  Simulation research
