[The determination of Niphensamide by UV spectrophotometry].
In this paper Uv spectrophotometry was used to determine Niphensamide. In this method, 372 +/- 1 nm was selected as a criterion for quantitative determination, and the absorptivity. E1 cm 1% = 556. The results indicated that a better linear-relationship between the absorbance and the concentration of the sample. When the concentration was ranged from 0.5 mg.L-1 to 40 mg.L-1, the correlation coefficient was 0.9999, and the mean rate of recovery reached 99.8%.
