| Abstract: | First deriyative spectrophotometry method was employed to determine salicylic acidin benzoic co. with 307urn as the detection wavelength. The interference resulting from thebase and benzoic acid was ruled out. The method was simple and quick. The average recoverywas D9.96% while the variation coefficient was 0.22%. |
