A high performance biosorbent, polyethylenimine (PEI)-modified biomass, was prepared by attaching PEI onto the surface of inactive Escherichia coli biomass. Wastewater containing platinum was collected from an industrial laboratory for inductively coupled plasma (ICP) and used for the recovery study. The maximum platinum uptake of PEI-modified biomass was enhanced up to 108.8 mg/g compared to 21.4 mg/g of the raw biomass. Kinetic experiments revealed that sorption equilibrium could reach within… CONTINUE READING
