摘要： To improve the physiochemical properties of gellan gum (GG), GG was modified with acrylamide and trimethylolpropane triglycidyl ether (TTE). The structure and morphology of modified GG were characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). The characteristic peaks at 3448, 2788, 1654, 1411, 1117 and 1044 cm(-1) in the FT-IR spectrum confirm the modification. The XRD and DSC data revealed that the modification enhanced the thermal stability of GG. SEM analysis suggested the modification introduced a porous microstructure, resulting in the adsorption of crystal violet. In addition, the adsorption capacity, thermal stability and swelling property of GGTTE3 were superior to GGTTE1, GGTTE2, GGTTE4 and GGTTE5.
