Description and Uses
Mono sodium citrate, or sodium dihydrogen citrate, is an acid salt with the chemical formula NaH2C6H5O7, or C3H4OH(COOH)2COONa. Since it has two remaining open spots on the citrate anion, it is used as a relatively strong sequestrant. It is used to prevent platelet clumping in blood samples. It is one of the 3 citric acid salts.
Sodium dihydrogencitrate has been employed:
- as reductant and stabilizer during the synthesis of Fe3O4 Pt core/shell particles
- in characterization of carbon-based electrode materials as cathode in half-cell configuration
- in electrochemical reduction of proton at carbon fiber electrode in the presence and absence of Pt nanoparticles
