Reduction or elimination of ~(87) Sr originated from~(87) Rb decay is the key to strontium isotope study on carbonate strata.The strontium isotope study on carbonate strata is based on that there is no~(87) Sr from ~(87) Rb decay after the strata were formed.The ion exchange column is no function for removing ~(87) Sr influence from the radioactive origin and can only remove Rb+,Ca~(2+),Ba~(2+)and so on,meanwhile,improves Sr ionization efficiency and avoids ~(87) Rb influence for ~(87) Sr test.Once the ~(87...
