Abstract
Effects of the ratio between H2O and surfactant concentrations, the pr esence of oxygen, and the pH of the aqueous phase on the formation of silver aggregates in reversed micelles were examined. It was demonstra ted that aggregates absorbing Light with lambda = 380 and 530 nm, whic h can be identified as aggregates of irregular shape or as aggregates forming a complex with organic ligands (surfactant molecules), are for med in reversed micelles under gamma-irradiation along with ordinary s pherically shaped silver aggregates having an absorption maximum at 43 0 nm. The presence of oxygen as well as H+ ions in significant concent rations results in processes that lower the probability of silver aggr egate formation.
