METHOD FOR EXTRACTION-PHOTOMETRIC DETERMINATION OF CHROMIUM (III) |
| 摘要 |
Method for extraction-photometric determination of shromium (III) ioncludes formation and extraction with toluene of dyed ion associate with organic reagents with following photometering. As organic reagents one uses sodium salt of 1-naphtoilgydrazone of pyruvic acid and cyan dye astrafloxin FF (chloride salt) and extraction with toluene of ion associates of chromium (III) is carried out at pH 5.7-7.8 with level of extraction 88,7 %. |
