Title: | Determination of fluoride with thorium nitrate by catalytic titration | Authors: | Gaál F. Abramović, Biljana Canić V. |
Issue Date: | 1-Jan-1978 | Journal: | Talanta | Abstract: | Amperometry, constant-current potentiometry and spectrophotometry were used to follow the course of catalytic titrations of fluoride and silicofluoride with thorium nitrate. The hydrogen peroxide-iodide system was used as the indicator reaction. Titrations were performed in 50% ethanolic acetate buffer, pH 3.6. Amounts of 3.70-6.85 mg of ammonium fluoride, 5.53-10.79 mg of potassium fluoride and 4.34-8.41 mg of sodium silicofluoride were determined with a maximum average deviation of 0.9%. The results obtained are in good agreement with those of comparable methods. © 1978. | URI: | https://open.uns.ac.rs/handle/123456789/9887 | ISSN: | 00399140 | DOI: | 10.1016/0039-9140(78)80044-7 |
