Recebido em 29/1/09; aceito em 22/5/09; publicado na web em 10/11/09 FLOW-INJECTION TURBIDIMETRIC DETERMINATION OF FLUOXETINE HYDROCHLORIDE IN PHARMACEUTICAL FORMULATIONS. A simple, accurate and precise flow-injection turbidimetric procedure for the determination of fluoxetine hydrochloride in pharmaceutical formulations is reported. The procedure is based on the precipitation of chloride of fluoxetine hydrochloride with silver nitrate solution and the yielded insoluble AgCl (s) was monitored at 420 nm. The analytical curve was linear in the fluoxetine hydrochloride concentration range 3.0 x 10 -5 -5.0 x 10 -4 mol L -1 with a detection limit of 10 µmol L -1 and, a sample throughout of 60 h -1 .
