Predmet rada ove doktorske disertacije je ispitivanje mogućnosti upotrebe otpadne
biomase na bazi kukuruza (oklasak kukuruza i kukuruzna svila) za adsorpciju Pb2+, Cu2+
i Zn2+ jona iz njihovih vodenih rastvora.
Karakterizacija uzoraka kukuruzne svile i oklaska kukuruza, u ovom radu vršena je:
određivanjem hemijskog i elementarnog sastava, određivanjem kapaciteta katjonske
izmene (KKI), tačke nultog naelektrisanja (pHPZC), određivanjem teksturalnih osobina
(BET), termijskom analizom (TGA / DTA), skenirajućom elektronskom mikroskopijom
i energijsko – disperzivnom rendgenskom spektroskopijom (SEM–EDX) i infracrvenom
spektroskopijom sa Furijeovom transformacijom (FTIR)...
This study aims to investigate the possibility of the usage of waste corn biomass (corn
cob and corn silk) for removal of Pb2+, Cu2+ and Zn2+ ions from aqueous solutions.
The characterization of corn silk and corn cob was performed by determination of
chemical and elemental composition, cation exchange capacity (KKI), point of the zero
charge (pHPZC), specific surface area and pore volume (BET analysis), thermal analysis
(TGA / DTA), scanning electron microscopy and energy dispersive X – ray analysis
(SEM – EDX) and Fourier transform infrared spectroscopy (FTIR)...
