摘要: 研究采用火焰原子吸收分光光度计测定污染土壤中生长的马齿苋(Portulaca oleracea)中的重金属铅、镉的含量。结果表明,马齿苋对污染土壤中铅和镉重金属离子具有较强的吸附萃取能力,而且马齿苋对镉的萃取能力强于铅。

Abstract: The content of Pb and Cd in Portulaca oleracea growing in soils contaminated by heavy metal were investigated by flame atomic absorption spectrophotometer(FAAS). The results showed that P. oleracea had strong extraction performance for the heavy metal ions in contaminated soils. And the extraction performance of P. oleracea to Cd was superior than that to Pb.

Key words: heavy metal, contaminated soils, Portulaca oleracea, herbaceous plant
