Abstract
This work was focused at investigating the improvement of the heavy metal removal process produced by the aquatic plant, Lepironia articulata for the treatment of wastewater. The bio-sorption of chromium (Cr) by the aquatic plant, Lepironia articulata signifies one of the key alternatives for heavy metal removal. The application of Lepironia articulate as bio-absorber of heavy metal hasn’t been studied yet. The bio-sorption of chromium (Cr) by the aquatic plant, Lepironia articulata near to Taman Anggerik, Kedah, Malaysia, was examined in wastewater contaminated with 4, 8, 12 and 16 mg l -1 of Cr. chromium concentrations were analysed in the wastewater regularly and in aquatic plant biomass after the experiments. The results revealed that maintaining pH at 6.1 ± 0.1, temperature at 22 ± 1 ºC and photoperiod at 12 h/j Lepironia articulata was capable of accumulating in its biomass 3, 15, 24 and 25 mg g -1 DM, for the four preliminary Cr concentrations selected. At the selected Cr concentrations, the heavy metal removal ranged between 62.45– 72.84%. The mass balance analysis carried out during the experiment revealed that approximately 40–63% of Cr (based on the preliminary Cr concentrations in wastewater) was eliminated through precipitation process. Thus, bio-sorption of Cr using aquatic plant, Lepironia articulata may bring a major point of improvement of the conventional wastewater treatment process.
