The ferrous alginate (Fe-Alg) microparticles were prepared via the microemulsion system.The effect of several factors such as the concentration of sodium alginate, the amount of surface-active agent, stirring speed and stirring time on the diameter and shape of the micropartichs were investigated.It is found that the diameter of the Fe-Alg microparticles can be 9.25μm when the concentration of Na-Alg is 2.0%, the ratio of surface-active agent and petroleum ether is 1 : 5 (g/mL) ,the stirring speed is 1000r/min,and the stirring time is 3h.
