General description

Citric acid is a weak organic acid that is commonly used for pH adjustment, as a chelating agent, as a buffering agent, derivatization and as starting material for the synthesis of citrate esters and other compounds.

Application

Citric acid has been used to prepare:
  • Phosphate citrate buffer for use in enzyme-linked immunosorbent assay.
  • Citrate-stabilized ceria aqueous sol, which was employed in the synthesis of cerium oxide nanoparticles.
  • Citric acid-Na2HPO4-buffered stock solution for use in the determination of fecal urease activity.
  • Anticoagulant citrate dextrose solution A (ACD-A), which is employed during the isolation of blood-derived endothelial progenitor cells.

Citric acid has also been used:
  • In a novel process which allows controlling of the particle size during the synthesis of palladium cuboctahedrons.
  • To prepare citric acid-derived carbon nanodots (CNDs) by bottom-up carbonization method.
  • As a bi-component chelating agent for the synthesis of Li4Ti5O12 (lithium titanate oxide) by a novel sol–gel method.
