摘要:

Two spectrophotometric methods for the determination of cefadroxil using Cu(II) and V(V) in sulphuric acid medium are described. Beer's law is obeyed up to 100 μg ml−1and the molar absorptivities are 2.10 × 103and 3.81 × 103L mol−1cm−1with copper and vanadium respectively. The two methods have been applied successfully to the analysis of the pharmaceutical preparations (Duricef oral suspension and capsules).
