SPECTROFLUORIMETRIC DETERMINATION OF ULTRA TRACE AMOUNTS OF LUTETIUM IN LANTHANUM, PRASEODYMIUM, AND DYSPROSIUM OXIDES

This paper analyses in depth the situation of Spanish analytical chemistry in recent years (particularly the 1990-1999 period). The analysis is preceded by an overview of Spanish scientific research in the period studied, which is followed by a bibliometric study and a review of the work of the most prominent current analytical research groups.
