Ss. Badawy et al., SPECTROPHOTOMETRIC STUDIES ON DETERMINATION OF CEFADROXIL WITH COPPER(II) AND VANADIUM(V) IN SULFURIC-ACID MEDIUM, Analytical letters, 26(3), 1993, pp. 487-497
Two spectrophotometric methods for the determination of cefadroxil usi
ng Cu(II) and V(V) in sulphuric acid medium are described. Beer's law
is obeyed up to 100 mug ml-1 and the molar absorptivities are 2.10 x 1
0(3) and 3.81 x 10(3) L mol-1 cm-1 with copper and vanadium respective
ly. The two methods have been applied successfully to the analysis of
the pharmaceutical preparations (Duricef oral suspension and capsules)
.
