Palladium nano-particles were synthesized by W/O microemulsion composed of nonionic surfactant (alkylpolyglycol ethers) named Marlipal O13/50, water and cyclohexane. The deposition of palladium nano-particles by chemicals demulsifying was investigated. The results showed that the sequence of deposition rate of palladium nano-particles from microemulsion under the action of different chemical demulsifier is 1,4-dioxane>THF>methanol>ethanol >n-butanol. The effects on interfacial tension and amphiphilicity of chemical demulsifier were studied. The results showed that the demulsifying process of microemulsion is also a process of interfacial tension increasing and a process gradually near to Lifschitz line.
