Abstract
A simple, precise, accurate, rapid, economical and sensitive ultraviolet spectrophotometric method has been developed for the determination of warfarin sodium in pharmaceutical preparations and environmental wastewater samples, which shows maximum absorbance at 310 nm in distilled water. Beer’s law was obeyed in the range of 2-30μg/ ml ,with molar absorptivity of 1.1 ×104 L.mol-1.cm-1 , relative standard deviation of the method was less than 1.8%, and accuracy (average recovery %) was 100 ± 1.0 . The method was successfully applied to the determination of warfarin sodium in some pharmaceutical formulations (Tablets) and industrial wastewater samples. The proposed method was validated by sensitivity and precision which proves suitability for the routine analysis of warfarin sodium in true samples.
