摘　　要：In this paper,a systematic study about the fluorescence spectrum characteristics of fluorescent whitening agent VBL in solution with the different effects,including the pH and solvent,was conducted.The fluorescence quantum yields in 25 different solvents were measured by the reference of quinine sulfate.According to these a new fluorescence determinations of the VBL in paper was built.The linear regression equation of the method is IF = 0.82 + 6.18 ×107c(mol/L) with a correlation coefficient(r) of 0.9992.The linear range of the method is from 0 to 2.85×10-6g/mL and the detection limit is 9.59×10-9g/mL.
