Adsorption of heavy metal from landfill leachate by wasted biosolids

The adsorption capacity of wasted solids that contained dead fungal biomass (Phanerochaete chrysosporium) was studied to remove cadmium, copper, zinc and iron from synthetic water and leachate. The biomass was produced due to the experiments conducted for bioconversion of wastewater for lignin perox...

Optimum removal of iron from leachate was 45.56% in every 1 L of leachate after 1/50 dilutions.
