Development of a particulate emulsifier by mechanochemical treatment and application to the liquid-liquid extraction process

摘要

A method to modify quartz particles to be a surface-active material by mechanochemical treatment was successfully developed.The obtained particles had sufficient properties for use as a particulate emulsifier.The particles prepared by mechanochemical treatment had a highly anisotropic surface,and the droplets emulsified by those particles were extremely large and stable because of their stonewall-like structure and high density.The obtained particulate emulsifier was applied to the liquid-liquid extraction process.Consequently it was clarified that the extraction rate increased 3.6 times according to the increase of interfacial area without reducing the mass transfer coefficient.
