| Abstract: | The enrichment of Pb2＋,Zn2＋ in the root,stem,leaf of the Alternanthera philoxeroides was determined by atomic absorption spectrometric method. The single, composite purification efficiency on Pb2＋,Zn2＋ in wastewater was preliminary studied. The results show that the purification ability of Alternanthera philo.Teroides can reach about 50%,but the cumulative removal rate is above 90% after the 5th day in low concentration of Pb2＋ ,Zn2＋. Accumulation of Pb2＋ ,Zn2＋ in roots and stems is higher than that in leave. |
