AbstractUnder the condition of visible light irradiation (lambda>450 nm), the degradation mechanism of microcystin-LR was studied using H(2)O(2) and FeY catalyst, which is prepared by means of loading Fe(2+) to the molecular sieve NaY. The results indicate that the degradation rate of microcystin-LR is up to 90% in the wide pH range using Vis/FeY/H(2)O(2) system. Based on the intermediates detected by LC-MS analysis, the possible pathways and three vulnerable oxidation sites are put forward: (1) the conjugated double bonds of the Adda chain, (2) the methoxy group of the Adda chain, (3) unsaturated double bond of the Mdha chain. FeY catalyst is of good stability, having catalytic activity after 5 times repetition, which indicates its potential application to the control of the alga wastewater.
