In this paper we studied the absorption condition of three common plant species, Aloevera var.chinensis, Chlorophytum comosum, and Autumn violet. We compared the enrichment ability of three plant species to lay the foundation for exploring the use of plants to repair mercury-contaminated soils. The amount of mercury uptake by three plant species was determined by cold vapor atomic absorption spectrometry. The results demonstrated that all plant species were able to take up Hg to an extent from a nutrient solution containing 800µg/L Hg and mercury-contaminated soils (total mercury content: 0.15-0.20 µg/g soils). However, the Hg translocation to the stems or leaves wasn’t high. The enrichment ability of Chlorophytum comosum was strongest among three plant species.
