Abstract
Spectrophotometric method has been proposed for the determination of Naproxen sodium (a non steroidal antiinflammatory drug). The method is based on the formation of a 1:1 ion pair with Bromocresol green and Bromothymol blue in the PH range over 3.2-4.4 to give blue colored chromogen. Under the proposed optimum condition, Beer's law was obeyed in the concentration range of 0.01-5mg/10 mL. The procedures are characterized by its simplicity with accuracy and precision.
