| Abstract: | The seperation features are studied about lanthanum and other rare-earth elements onexchanging resin of strong acidic cation. Accord ing to the d ifference of the stable constants oflanthanum and other rare earths and sulfosalicylic acid, lanthanum is separated from the other fourteenrare-earth elements. The analytic result from the standard recovery rate , synthetical samples , mixedrare oxides and soandard samples of monazite by means of separation and determination has shown thegood precision and accuracy of this method. |
