Influence of Stirring Time on the Electrochemical Synthesis of Silver Nanoparticles: Size and Stability Analysis

This study explores the impact of stirring time on the size distribution and stability of silver nanoparticles (Ag-NPs) synthesized through an electrochemical method. High-purity silver rods and distilled water were used in an electrochemical cell, with varying stirring times (30 minutes and 1 hour) to observe differences in nanoparticle formation. UV-Visible spectrophotometry revealed characteristic plasmon resonance peaks at 395 nm for 30-minute stirring and 400 nm for 1-hour stirring, indicating differences in size distribution. Scanning Electron Microscopy (SEM) analyses showed that nanoparticles with a 30-minute stirring time had
sizes ranging from 40 to 60 nm, while those with a 1-hour stirring time ranged from 30 to 50 nm. These findings underscore the importance of stirring time in achieving desired nanoparticle characteristics, which is crucial for applications in medical devices, coatings, and antimicrobial treatments
