【 摘 要 】

This study investigates the characterizations of fabricated MnO2-amberlite using for alizarin photocatalytic degradation. Mixtures of fabricated MnO2-amberlite were magnetically stirred for 6-, 12-, 18-, 24-, and 30h, respectively. Some functional groups of amberlite like C-O, C-C and N-H were eliminated after doping with MnO2 as shown by FTIR (Fourier Transform Infrared) spectra in the range of 1600 - 900 cm-1, change in crystalline structures due to linkage of MnO2 with amberlite was observed at 2θ of 25° in the XRD (X-ray diffraction) analysis, and change in surface morphology due to MnO2 doping in amberlite was investigated in SEM (Scanning electrone microscope) examination. Since alizarin is a harmful material causing environmental problem, this preliminary study found that the 18h-stirred fabricated MnO2-amberlite showed the best photocatalytic properties, which enabled to degrade 23.4% alizarin under 1h UV exposure without heating.
