Microemulsion with Span/Tween as Mixed-surfactant and Synthesis of Iron Nanoparticles
Span/Tween为混合表面活性剂的微乳体系研究及纳米铁制备

Three kinds of microemulsion systems with different compositions formed by iso-octane/Span80Tween60/n-butanol, edible oil/Span80Tween60/n-butanol and edible oil/Span80Tween60/n-butanol were studied. The system of iso-octane/Span80Tween60/ n-butanol is the best choice for the purpose of microreactor when the hydrophilelipophile balance value is 14, content of emulsion (mass ratio of surfactant to oilphase) is 0.5, Co/S=0.5 (Co/S is the mass ratio of co-surfactant-to-surfactant). The nanosized iron particles with average diameter of 80 nm were synthesized with the system.
