| titleOfInvention | Method for rapidly testing Rb-Sr isotope in rock sample |
| abstract | The invention provides a method for rapidly testing Rb-Sr isotopes in a rock sample, which is to separate and purify a high-purity Rb and Sr sample from the rock sample, and dissolve and dilute the high-purity Rb and Sr sample to a sample solution with proper concentration by hydrochloric acid; then taking a proper amount of diluted phosphoric acid and TaF 5 The emitting agent is sequentially coated on the surface of a high-purity Re filament, Sr and Rb sample liquid is sequentially coated after evaporation, a thermal ionization mass spectrometer is used for testing after evaporation, the ionization temperature is adjusted to 600-720 ℃, Rb isotope is firstly tested, the temperature of the filament is adjusted to 1300 ℃ and is kept for 2-3 minutes, a trace amount of Rb sample coating on the surface of the filament is burnt, and finally the temperature of the filament is adjusted to 1350-1500 ℃ and Sr isotope is tested. The method realizes high-precision measurement of the rubidium and strontium element concentrations and the strontium isotope ratio on the same filament, greatly improves the measurement efficiency, greatly reduces the measurement cost and labor consumption, and has wide application prospect in geological times and geochemical tracing research. |
