CdS nanoparticles were synthesized in water solution,the surface of CdS nanoparticles was modified with poly-4-pentenoic acid under ultrasonic irradiation.With CdS/PPA nanoparticle solution as fluorescence probe combined with synchronous fluorescence spectrometry,a method for determination of BSA in water solution was developed.The working curve for determination of BSA is ΔF=117.50+29.55^c(1×10^-6 g/mL),the linear range is 0.5×10^-6~30×10^-6 g/mL,the limit of detection is 0.12×10^-6 g/mL.In addition,the present method was applied to quantifying BSA in synthetic samples.
