Spectrophotometric, potentiometric and conductometric methods are developed for the determination of bupropion hydrochloride (BUP) in pharmaceutical tablets. For the first method, original UV-spectrophotometry, 252 nm was determined as the optimum wavelength and used for the determinations. For the other method, second derivative UV spectrophotometry, the absorbances were measured at 217.4 and 221.8 nm and the distance between these extremum values was determined according to peak to peak method. Two spectrophotometric methods were validated over the concentration range of 5.72 - 20.03 Ug/mL. The limit of detection and limit of quantitation values of original UV-spectrophotometry were 0.75 ug/mL and 2.28 ug/mL. Also, these parameters were determined as 0.23 ug/mL and 0.68 ug/mL respectively, for the second derivative UV spectrophotometry. Developed methods were fully validated and the applicability of the methods for the determination of BUP in pharmaceuticals were demonstrated. Also, simple potentiometric and conductometric methods were developed and the applicability of these methods were demonstrated. The results of four analytical methods were compared with ANOVA test and no significant difference was found statistically As a result the develoned methods could he nronosed to the rutin content analysis to be simple, cheap, accurate, and precise.
