1 sty 2014 · Disodium hydrogen citrate and potassium dihydrogen citrate behave similarly at low concentrations with ν ~ 3, but sodium dihydrogen citrate is dissociated only to Na + and H 2 Cit − having ν ≤ 2 (Fig. 5.5). In all cases, sodium salts have lower value of ν than corresponding potassium salts.
1 lip 2017 · Herein, we present a convenient method for quantitative spectrophotometric determination of citrate ions in aqueous solutions in the middle-UV range. It involves measuring the absorbance of citric acid at 209 nm under suppressed dissociation at pH < 1.0 in the presence of hydrochloric acid.
18 USP monographs for the assay of citric acid or phosphate in USP 27-NF 22. The method was evaluated in terms of linearity, precision, accuracy, ruggedness, and limit of quantitation for phosphate and citrate.
The citrate test is often part of a battery of tests used to identify gram-negative pathogens and environmental isolates (10). For instance, test kits such as the API-20E (bioMerieux) and Enterotube II (BD Diagnostics) include citrate utilization medium as one of the diagnostic tests.
1 lip 2016 · The crystal structure of disodium hydrogen citrate sesquihydrate has been solved and refined using laboratory X-ray single-crystal diffraction data, and optimized using density functional techniques.
