Determination of Lead and Zinc inAlternanthera philoxeroides from Wastewater by Atomic Absorption Spectrometry

DU Qing

Abstract

The enrichment of Pb2+,Zn2+in the root,stem,leaf of theAlternanthera 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 ofAlternanthera philoxeroidescan 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.
