| titleOfInvention | Method of extraction photometry analysis of gold |
| abstract | The invention relates to methods for the extraction - photometric determination of gold (I), allows to increase the sensitivity and selectivity of the analysis and can be used in the analysis of various gold-bearing objects, including high-purity substances. Gold is converted to the ion associate of the dicyanide complex with the N. N-dimethyl-dinotricarbocyanine (DID) dye. To do this, potassium ferrocyanide is added to the analyzed solution to a concentration of (0.4-5.0) M, DID to a concentration (0.6-2.0 M and extracted with a mixture of toluene and ethyl acetate (1; 4). Method allows you to increase the selectivity of the analysis (almost all metals do not interfere with the determination) and sensitivity up to µg / ml (compared to 0.16 µg / ml for the prototype). 1 Cp f-crystals, Table 7 d |
