Title: | Automatic titrimetric determination of iodide in some pharmaceutical contrasting preparations | Authors: | Abramović, Biljana Horváth K. Gaál F. |
Issue Date: | 1-Jan-1993 | Journal: | Journal of Pharmaceutical and Biomedical Analysis | Abstract: | Automatic titrimetric methods with catalytic, spectrophotometric and potentiometric monitoring of the course of titration were applied for determination of iodide content in iopanoic acid, 2-(3-amino-2,4,6-tri-iodobenzyl)butyric acid, as well as in the mixture of sodium amidotrizoate (sodium 3,5-diacetamido-2,4,6-tri-iodobenzoate), and meglumine amidotrizoate (N-methylglucamine salt of 3,5-diacetamido-2,4,6-tri-iodobenzoic acid), in some pharmaceutical contrasting preparations. After combustion of the sample in an oxygen atmosphere and absorption of products in hydrazine sulphate solution, the iodide present was titrated with a standard solution of silver nitrate. In catalytic titrations, the system persulphate-sulphanilic acid (acetate buffer pH 4.35) in the presence of 2,2′-bipyridine as an activator served as the indicator reaction. The results obtained were compared with those of the official methods. Amounts of iodide of about 1.2 mg per aliquot of analyte were determined with a standard deviation less than 1.9%. © 1993. | URI: | https://open.uns.ac.rs/handle/123456789/14727 | ISSN: | 07317085 | DOI: | 10.1016/0731-7085(93)80156-U |
