Spectrophotometric Studies on Determination of Cefadroxil with Copper(II) and Vanadium(V) in Sulphuric Acid Medium

Abstract

Abstract 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−1 and the molar absorptivities are 2.10 × 103 and 3.81 × 103 L mol−1 cm−1 with copper and vanadium respectively. The two methods have been applied successfully to the analysis of the pharmaceutical preparations (Duricef oral suspension and capsules).
