Abstract

Lanthanum was determined in phosphoric rock and in its products obtained in the process of production of phosphoric acid and fertilizers in Mexican plants. The method used for the determination of lanthanum was neutron activation analysis. It is observed that the concentration of lanthanum is higher in the fraction of calcium salts.
