| Abstract: | Preparation of alginate calcium microspheres and alginate calcium-quaternary ammonium complex micro- spheres by emulsification-gelation was reported. The influences of experimental conditions on alginate calcium parti- cles size and morphology, such as, the concentration of sodium-alginate, stirring speed and the relative proportion of organic phase to aqueous phase, were investigated. And the morphologies of alginate calcium-quaternary ammo- nium complex microspheres were also investigated by Fourier transform infrared spectroscopy （FTIR） and micro- scope. The results indicated that alginate calcium-quaternary ammonium complex microspheres with good morpholo- gy could be obtained under the optimum conditions. |
