Removal Of Pb(II) Using Bio-Char from Microwave Pyrolysis Carbonization of Water Hyacinth

Water hyacinth is an invasive plant which breeds very quickly. It had led to many adverse environmental events such as river blockages and fish endangerment. This study used microwave to pyrolysis water hyacinth and activate it to produce heavy metal absorbent and improve the removal of Pb(Ⅱ). Compared with conventional method, it simplify the produce process, As the dose increased to 0.25g, the absorption efficiencies of two absorbents all achieved to nearly 100%.The results indicated that the adsorption ability of WHB is close to AWHB
