| titleOfInvention | Method of determining samarium,europium and gadolinium |
| abstract | The invention relates to methods used in analytical chemistry, and allows for the possibility of separate determination of samarium, europium, gadolinium and terbi in the presence of other rare earth elements. The method involves the introduction of phthalexone-S into one aliquot, semiftalexon-S into another aliquot, the subsequent introduction of ammonium and benzylthiocechevine into both aliquots of the quaternary ammonium salt, extraction with p-butanol, subsequent registration by spectrophotometric method and calculation of the content of elements according to the difference of definitions in two aliquot In addition, phtapexon-S and semiftalexon-I are used to determine terbi, gadolini semiftapexon-S and O -cresol-phtalexon-S are used to determine gadolinium, O-cresolphthalexon-S and seven-0-cresol-phthalexon-S are used to determine eurobi Semi-Ogkrezolftepekson-S and timolftalekson-S. 1 tab. jO |
