Abstract:

Lead in wastewater is one of hazardous pollutants in environmental. Finding an economic and effective method for removing Pb2+ from wastewater has been the hot point problem in water treatment researches. Low-cost bio-adsorbents are characterized by its simplicity of operation and good effectiveness on the removal of heavy metal ions. The application of bio-adsorbents for removing Pb2+ from wastewater is summarized and discussed. The influencing factors and mechanisms of low-cost bio-adsorbents on the treatment of Pb2+-containing wastewater are analyzed. The problems and development trend of the research on bio-adsorbents at present are pointed out.

Key words: bio-adsorbents, adsorption, Pb2+-containing wastewater, wastewater treatment
