SPECTROPHOTOMETRIC DETERMINATION OF IMIPRAMINE HYDROCHLORIDE USING AMMONIUM PEROXIDISULFATE AND NIOBIUM(V) THIOCYANATE COMPLEX

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.
