초록

영어
In this study, a high performance biosorbent, PEI-modified biosorbent, was developed by cross-linking with polyethylenimine (PEI) on the surface of inactive waste biomass of Escherichia coli, which is generated from a Lphenylalanine fermentation plant. Platinum-bearing wastewater was collected from industrial analytical laboratory and was used as a model platinum waste
solution. Sorption performance of the PEI-modified biosorbent was evaluated using kinetic and isotherm experiments and compared with that of the raw biomass. The maximum platinum uptake of PEI-modified biomass was as high as 108.8 mg/g compared to 21.4 mg/g of raw biomass. The kinetic experiments revealed that sorption equilibrium could be attained within 60
min. The results of FTIR and XPS analyses of Pt-unloaded and Pt-loaded PEImodified
biosorbents showed that the electrostatic interaction would be the main binding mechanism between the platinum ions and binding sites on the surface of biosorbents. Metallic form of platinum in ash could be recovered by incineration, with over 98.7% of recovery efficiency. Furthermore, TEM, XPS and XRD results confirmed that the forms of platinum were existed as Pt0 and Pt2+ (as platinum oxide) in the incineration ash. Therefore, it can be concluded
that the developed PEI-modified biosorbent can be used for platinum recovery through a combined process of biosorption and incineration.
