土壤铜污染的影响因素及其修复技术研究

铜污染引起的生态和环境问题已受到人们的高度重视。土壤中铜对生物的毒害作用主要取决于它的赋存形态。土壤组成成分、pH值、土壤中其它污染物以及环境因素都会对铜在土壤中的赋存形态和吸附解吸产生影响,因此,不同土壤对外来铜污染的缓冲能力有一定的差异。已经有学者研究出针对铜污染土壤的几种有效的修复技术,目前主要是植物修复技术。现有修复技术中仍存在一些问题,其引导着今后相关研究的发展方向。

Research on the Influence Factors of Copper Contamination on Soil and Its Remediation Technology

Ecological and environmental issues of copper contamination on soil has been given increasing attention.Damage of copper in soil depends on its morphology mainly.Soil composing component,soil pH,other pollutants in soils and environmental factors have effects on arsenate on adsorption and desorption of copper.Accordingly,there were differences among buffer capacity of soil.Recent years many scholars have researched some effective approaches,phytoremediation technology is stated mainly.There are still some p...
