ABSTRACT
The spectrophotometric determination of trace amounts of diclofenac was carried out by liquid-liquid extraction using acridine yellow with a flow system. The determination of diclofenac sodium in the range of 3-80 micrograms ml-1 was possible with a sampling frequency of 40 samples h-1. The method was satisfactorily applied to the determination of diclofenac in pharmaceutical preparations.
