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.
