摘要：

The enthalpies of precipitation of ZnS nanoparticles within water containing reversed micelles of sodium bis(2-ethylhexyl) solfosuccinate, L-alpha phosphatidylcholine, tetraethyle-negycol-mono-n-dodecyl ether and didodecyldimethylammonium bromide as a function of the molar concentration ratio R (R=[water]/[surfactant]) were measured by calorimetric technique. The results indicate that the energetic state of ZnS nanoparticles confined in the aqueous core of the reversed micelles is different from that in bulk water. Effects due to nanoparticle size, adsorption of HS- ions on the nanoparticle surface and interactions between nanoparticles and water/surfactant interfaces are discussed.
