| Abstract: | In thispaper, a rapid and simple method for the determination of the total rare earths by reverse flow injection analysis is described. It based on the procedure of rare earths in 1.2 mol/L HC1 as carry stream and injecting DBC-CPA. The consumption of DBC-CPA is minimized and the permi-ting amounts of Ca and Fe are increased by about one order of magnitude as compared with that of manual method. The method has been used to determination of the total rare earths in rare earth aluminium alloys with satisfactory results. |
