Abstract
Soil samples are extracted by sequential extraction to assess metal speciation and its bioavailability, and each fraction will be tested with an AAS instrument. The bioavailability of spiked soil with Ni metal showed the most distribution detected in fraction 3 (bound to Fe and Mn Oxides) were percentage 38-58%. Basil (Ocimum Africanum L) plants, which will be the media for the mobilization study of heavy metals, then plant were wet destruction and detected by ICP-MS. Furthermore, the ability of Basil to absorb Nickel showed a higher accumulation detected in roots, followed by stems and leaves (C-roots>C-stems>C-leaves). And different concentrations, it is known that the higher the concentration of metal spiked into the soil, the higher the concentration of nickel-metal that can be absorbed and detected in soil and plants. So, Basil able to hyperaccumulator nickel but low, cause TF < 1 and BCF < 2.
