摘要: The mechanism of formation cadmium sulfide and zinc ultrafine particles in reverse micelles has been studied, using sodium bis(2-ethylhexyl) sulfosuccinate (AOT)/isooctane as a micellar solution. particle process was followed by the change UV-visible absorption spectra. effects reactant concentration water content on diameter were also investigated. Particle nucleation growth occurred very rapidly complete within 0.02 s, coagulation. coagulation rate constant found to be controlled only intermicellar exchange rate, initial stage. With increasing diameter, dominated statistical distribution among micelles. As approached that core micelle, became restricted size
