It is found that the fluorescence of curcumin is greatly enhanced by La3+ in the prescence of sodium dodecyl benzene sulfonate (SDBS). Based on this, a sensitive fluorimetric method for the determination of curcumin in aqueous solution is proposed. In the HOAc-NaOAc buffer, the fluorescence intensity of curcumin is proportional to the concentration of curcumin in the range of 0.0074-7.4μg·mL-1 and the detection limit is 3.66ng·mL-1. The actual samples are satisfactorily determined.
