| Abstract: | A method for determination of 2 hydroxy 3 naphthoic acid in naphthol AS by double wavelength UV spectrophotometry is described. The 2 hydroxy 3 naphthoic acid was extracted from substituted benzene solution of commercial samples with 0.05% sodium carbonate water solution, pH of detction solution, 10.5 12.0. The results showed that the recoveries were between 98.6%~101.2%, RSD 0.86%, detection limit 0.01%. Five commercial samples were determined. |
