Spectrophotometric Method for the Assay of Aspirin

Abstract:

A selective method was developed for the determination of aspirin by Spectrophotometric method .The spectra (range: λ=200~320 nm) were processed. The linear ranges of aspirin was at 50.28 ~ 125.7μg • mL^-1 .the aspirin showed good linear correlation.The ultraviolet spectrophotometry data of the samples were also used to evaluate the samples’ quantitative composition.It was shown that recovery of the method by standard addition method was respectively valued 102.06% for aspirin .The method was simple,reliable,accurate,reproducible with high sensitivity and selectivity.
