Abstract:
|
Heavy metals are major toxic pollutants with severe health effects on
humans. They are released into the environment from a variety of industrial
activities. Cadmium, lead, zinc, chromium and copper are the most toxic
metals of widespread use in industries such as tanning, electroplating,
electronic equipment manufacturing and chemical processing plants. Heavy
metals contribute to a variety of adverse health environmental effects due to
their acute and chronic exposure through air, water and food chain.
Conventional treatment methods of metal removal are often limited by their
cost and ineffectiveness at low concentrations. Adsorption, the use of
inactivated biomass as adsorbents offers an attractive potential alternative to
their conventional methods. Mango peel and Alisma plantago aquatica are
naturally occurring and abundant biomass can offer an economical solution for
metal removal.The Cd(II), Pb(II), Zn(II), Cr(III) and Cu(II) adsorption by milled
adsorbents of mango peel and Alisma plantago aquatica were evaluated in
batches. |
