摘要

The possibility of using phytoremediation with weed plant species in Thailand to remove chromium (Cr) from soil was conducted. The weed plant species were studied because they have no value and are burdens to the environment as agriculture waste. Phyllanthus reticulatus was chosen for this ability to accumulate total chromium (TCr). This plant species was studied in pots at a nursery. TCr accumulation capacities of roots, stems and leaves on this plant was 390.6, 61.5 and 58.7mg/kg of plant on a dry weight basis at days 30, respectively, at a pulse hexavalent chromium [Cr (Ⅵ)] concentration. The Cr(Ⅲ) uptake by Phyllanthus reticulatus occurred mainly in roots, stems and leaves at 291.4, 3.4 and 3.3mg/kg of plant on a dry weight basis, respectively, Within 30 days of dosing, Phyllanthus reticulatus had Cr(Ⅵ) accumulation in roots, stems and leaves of 99.2, 58 and 55.3mg/kg of plant on a dry weight basis of the Cr(Ⅵ) input, respectively. The results on hexavalent chromium accumulation and translocation in plant tissues suggest that Cr was removed mainly via phytoextraction and that Phyllanthus reticulatus is more suitable for the phytoremediation of Cr contaminated soil.
