Rizofiltrasi Logam Pb (Plumbum) pada beberapa Jenis Tumbuhan Air
Abstrak: The research about
rhizofiltration of Pb in several species of aquatic plant had been conducted in
a greenhouse of Biology Faculty, Jenderal Soedirman University. The aims of
this research were to evaluate the aquatic plant species which has Pb
accumulative characteristic and to determine Pb concentration tolerated by
those plants. This research was used experimental method with split plot
design. The main plot was kind of aquatic plant of Hydrilla verticillata (L.f),
Pistia stratiotes L, and Salvinia molesta D.S.Mitchell. The Pb (NO3)2
concentrations of 0, 5, 10, 15 mg/l were as sub plot. Each treatment was replicated for 3 times.
The parameter observed were biomass (raw weight and dry weight), the Pb
absorbed whether in root and shoot, and chlorophyll content. Data collected
were analyzed using F test continued by LSD. The result of this research showed
that both Pistia and Salvinia planted in 10 mg/l media were able to accumulate
high Pb concentration. However, Pistia were able to accumulate Pb concentration
mostly in root and only part be translocated in shoot. Whereas Salvinia was
able to translocate Pb concentration in shoot higher than those in of
Pistia. The implications of these
results for rhizofiltration are discussed.
