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.

Fe2O3/attapulgite(ATP) catalyst was successfully prepared for Fenton reaction to degrade an anion surfactant, sodium dodecyl benzene sulfonate(SDBS)，in an aqueous solution. BET, SEM, FT-IR were performed to characterize Fe2O3/ ATP catalyst. Comparative studies indicated that the SDBS degradation ratios were much higher in presence of Fe2O3/ATP and H2O2 than those in presence of Fe2O3/ATP or H2O2 only, which suggested that the Fe2O3/ATP-catalyzed Fenton-like reaction governed the SDBS removal process. It also can be seen that Fe2O3/ATP-catalyzed Fenton-like reaction almost has the same efficiency as homogeneous Fenton reaction, while the former can be reused and has no secondary pollutants.
