Abstract
Abstract Ag nanoparticles were transferred from water phase to toluene phase via a remarkably simple one-step route under the effect of phase-transfer inducer dimethyldioctadecylammonium chloride (DDAC), where no special stabilizer was needed. However, the water layer changed into emulsion, making it difficult to observe the change in water phase. By the help of centrifugation, the emulsion was destroyed, and the water layer became clear. The effect of the inducer DDAC concentration is checked, and it was found that 4 × 10 −4 mol dm −3 of DDAC was the optimum concentration for phase transfer of Ag nanoparticles.
