Abstract

A simple, economical and sensitive UV spectrophotometric method has been developed for the determination of allopurinol in environmental wastewater samples and, pharmaceutical preparations which shows maximum absorbance at 250 nm in distilled water. Beer’s law was obeyed in the range of 1 - 20 μg/ ml, with molar absorptive of 0.628 x104 l/mol.cm L.mol-1.cm-1 .The method was successfully applied to the determination of allopurinol 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 allopurinol in true samples.
