Abstract:

The core-shell magnetic xanthogenated chitosan for heavy metal catcher(FSiCS) was synthesized by using chitosan,carbon disulfide and Fe3O4 as raw materials and glutaraldehyde as cross-linking agent through ultrasonic assisted synthesis.The removal rate of Sb(Ⅲ) in aqueous solution was measured to evaluate the performance of FSiCS.The FSiCS showed the best performance when the amount of CS2 was 3.0 mL,concentration of NaOH was 90 g/L,reaction time was 60 min+60 min,ultrasonic power was 160 W,amount of glutaraldehyde was 150 μL,reaction temperature was 50 ℃.The structure was characterized by Fourier transform infrared spectroscopy(FTIR),scanning electron microscopy(SEM).FTIR showed that FSiCS contained sulfur groups or chemical bonds such as —SH,N—C=S,C=S and C—S,which could coordinate with Sb(Ⅲ).SEM showed that FSiCS had a particle size between 100~250 nm,and the particles were spherical or polygonal with clear edges and corners.
