A detailed investigation of the photodegradation of MG has been carried out in the ZnO suspension irradiated with visible light. The effects of various factors - viz. pH values, amount of catalyst, initial dye concentration, and the presence of NaCl, Na(2)CO(3), H(2)O(2), and Na(2)S(2)O(8) - on the degradation efficiency were studied. Thirty-two intermediates were separated, identified, and characterized by high-performance liquid chromatography-photodiode array-electrospray ionization-mass spectrometry (HPLC-ESI-DAD-MS) technology, giving us insight into the pathways of the degradation process.en-US學科：生物化學暨細胞分子生物學科期刊論文article
