Abstract: Heavy metal pollution of soil has been increasingly serious environmental concerns. Phytoremediation technology is a kind of economy and environmental friendly treatment to remove heavy metals in soil with hyperaccumulation plants. To screen hyperaccumulator which can extract heavy metal cadmium from contaminated soils, a pot experiment was developed. The results showed that: the Cd contents of Sedum tatarinowii Maxim, Hibiscus syriacus L. and Brassica oleracea L. var. acephala DC. in above-ground parts were great than 10 mg/kg. The Cd-transfer ratio of Sedum tatarinowii Maxim was 3.06, the highest one among all tested materials. Cd in under-ground parts of Nerium indicum Mill., Amorpha fruticosa L. and Hibiscus syriacus L. could be great than 50 mg/kg. The results indicated that 5 plants mentioned above could be grow, and fix and eliminate Cd in Cd-polluted soils.
