A new simle and rapid spectrophotometric method for the determination of diclofenac sodium is described. Diclofenac Sodium gives yellow colour when reacted with sodium nitrite in the presence of HCI with a maximum absorbance at 390 nm. The Beer's law is obeyed in the range of 0.05-0.60 mg of diclofenac sodium.
