    General description

    Citric acid is an organic acid commonly used as a chelating agent, a buffering agent, for pH adjustment and derivatization.[8]

    Application

    Citric acid has been used to prepare:
    • Phosphate citrate buffer for use in enzyme-linked immunosorbent assay.[4]
    • Citrate-stabilized ceria aqueous sol, which was employed in the synthesis of cerium oxide nanoparticles.[1]
    • Citric acid-Na2HPO4-buffered stock solution for use in the determination of fecal urease activity.[2]
    • Anticoagulant citrate dextrose solution A (ACD-A), which is employed during the isolation of blood-derived endothelial progenitor cells.[6]

    Citric acid has also been used:
    • In a novel process which allows controlling of the particle size during the synthesis of palladium cuboctahedrons.[7]
    • To prepare citric acid-derived carbon nanodots (CNDs) by bottom-up carbonization method.[5]
    • As a bi-component chelating agent for the synthesis of Li4Ti5O12 (lithium titanate oxide) by a novel sol–gel method.[3]
