Abstract:
The aims of this research was to determine the ability of velvetleaf as a phytoremediator for lead (II) ion. Pb ion in solution and velvetleaf were analyzed using atomic absorption spectrophotometer. The results showed that Pb concentration was decrease at days 0; 3; 6 and 12 amount 19.159; 0.333; 0.156 dan 0.010 mg/L. The accumulation of Pb ion in stems and leaves which measured at the same periods were 20.45, 364.98; 521.64 and 309.01 mg/Kg respectively. The results showed that velvetleaf (Limnocharis flava) was potential as phytoremediator for lead (II) ion caused its ability to adapt in the environment that exposure of Pb and to accumulated Pb2+ ion into the leaves and stems.
