| Abstract: | Crosslinked cassava starch microspheres（CCSM） were prepared by crosslinking of cassava starch and N,N′-methylene-bis-acrylamide（MBA） in inverse suspension.The polymer was characterizated by scanning electron microscopy（SEM）、Fourier transform infrared spectroscopy（FTIR） and X-ray diffractometer（XRD）.The technique of polymerization was studied,and the statics adsorption behavior of CCSM to Fe3＋ was investigated.The photo of SEM indicated that the CCSM are sherical particulates with rough surface and small particle diameter.The optimum polymerization conditions were decided by experiments as follows： 2.4 g of cassava starch,0.5 g of MBA,0.6 g of K2S2O8,1∶4 of the water-oil phase volume ratio,polymerization temperature at 65 ℃ and polymerization time for 2 h.The adsorption results showed that the CCSM have good adsorption property to Fe3＋. |
