摘　　要：测定了多种表面活性剂构成的反相微乳液体系对于水及盐溶液的载量,找到了一种具有较高氯化铁溶液载量的反相微乳液体系Egepalco-520/环己烷(或石油醚PE)/H2O.利用该体系制备纳米氧化铁的粒径与形态和盐溶液的浓度、加入量及表面活性剂/油的比有关.在表面活性剂/油比较高时,可以制备出粒径小于10nm的氧化铁,但所制备的氧化体的结晶性较差.Loading amounts of water phase in several microemulsion systems were measured.Igepalco-520/cyclohexane or PE/H2O system was found with high loading amount of iron chloride solution.The size and morphology of particles prepared via microemulsion were determined by the concentration,solution amount and the ratio of surfactant/oil phase.The nanometer size particles with diameter less than 10 nm could be produced using high surfactant/oil phase ratio.But the crystallizability of iron oxide prepared via microemulsion was poor.
