Description

Application

Sodium acetate trihydrate has been used:

• as a component of citrate-acetate buffer for hydroxyproline assay
• to prepare buffered salt solutions for ultrafiltration experiments
• to prepare acetate buffer solution for the electrochemical synthesis of indium tin oxide/gold nanoparticles/nickel oxide/poly(Pyrrole-N-propionic acid) (ITO/GNPs/NiO/poly(PPA)) electrode

Biochem/physiol Actions

Sodium acetate trihydrate (SAT), an inorganic salt hydrate has been the focus of numerous scientific studies on its potential as a heat energy storage phase transition material (PCM).
