Descrição

Descrição geral

Sodium citrate tribasic dihydrate is the tribasic dihydrate sodium salt of citric acid.

Aplicação

• Kinetic Study of Silver Nanoparticle Formation: This study examines the influence of varying concentrations of sodium citrate tribasic dihydrate in the synthesis of silver nanoparticles. The sodium citrate acts as a reducing agent, impacting the formation and stability of the nanoparticles. The detailed kinetic analysis contributes to understanding the nucleation and growth mechanisms of silver nanoparticles in the presence of sodium citrate tribasic dihydrate (SA Diaz - The Undergraduate Research Journal at the University of Northern Colorado, 2019).
