Description
- 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.[1]
- Application: Citric acid has been used to prepare:Phosphate citrate buffer for use in enzyme-linked immunosorbent assay.[2]Citrate-stabilized ceria aqueous sol, which was employed in the synthesis of cerium oxide nanoparticles.[3]Citric acid-Na2HPO4-buffered stock solution for use in the determination of fecal urease activity.[4] Anticoagulant citrate dextrose solution A (ACD-A), which is employed during the isolation of blood-derived endothelial progenitor cells.[5]Citric acid has also been used:In a novel process which allows controlling of the particle size during the synthesis of palladium cuboctahedrons.[6] To prepare citric acid-derived carbon nanodots (CNDs) by bottom-up carbonization method.[7]As a bi-component chelating agent for the synthesis of Li4Ti5O12 (lithium titanate oxide) by a novel sol–gel method.[8]
