| titleOfInvention | QUANTITATIVE ANALYSIS OF THIOMETH AND SODIUM FLUORESCIN IN THEIR JOINT PRESENCE IN PLASTIC WATERS |
| abstract | Quantitative analysis of thiourea and sodium fluorescein with their joint presence in formation waters, in which the test sample is separated from oil, purified from mechanical impurities, clarified in a centrifuge and added to the resulting alkali solution for quantitative determination of sodium fluorescein using a luminescent method, characterized in that the concentration thiourea and sodium fluorescein are determined by the interpolation method according to the results of three cumulative measurements, one of which relates to the test sample, and the other two to model solutions prepared from the test sample by fixed dilution of the source formation water (without indicator) and a fixed addition of the test indicator in such an amount that the signal of one of the model solutions is larger and the other is smaller than the signal of the test sample, and for analysis of thiourea in the test A fixed amount of sodium pentacyanoquaferriate and sodium fluorescein are added to the sample in an amount equal to that measured in the test sample by the luminescent method. |
