| Abstract: | The analytical method for determinatin of the total rare earth in steel using a direct-reading spectrograph is described;the validity of representation of the total amount of the rare earth in steel by the light rare earth verified;the effective preparation conditions determined;and the interference of the coexisting elements checked.Results show that the analytical error is controlled within the reproduction limit of GB/T223.49-94 and the analytical cycle is less than 8 minutes. |
