ABSTRACT Analytical determination of Demeclocyline (DMC) and Vanadium (IV) in pharmaceutical formulation is carried and based on a colour reaction between DMC and Vanadium (IV) forms orange coloured complex with DMC in a buffer of PH-6. The method can be conveniently used for the determination of vanadoium(IV) and DMC in the ranges of 0.51 to 4.07 mg/ml. and 0.004 to 0.040 mg/ml respectively. The method is successfully applied for the determination of DMC in pharmaceutical formulation. Effect of various parameters in his pH, metal ion concentration, drug concentration, of vary solvents is studied. The optimum condition are observed for the determination of vanadium and the drug. Keywords: Spectrophotometric method1, DMC and vanadium system. [Download Article] [Download Certifiate] |
