Abstract:Microcystins,a group of hepatotoxin produced by cyanobacteria,have proven unreliable to be removed from water by conventional water treatments. This paper introduces the latest research development of degradation of microcystin-LR (leucine arginine) by TiO 2 photocatalysis. The destruction mechanism and kinetic modeling are analyzed under different concentration of microcystin-LR. Major pathways for the photocatalytic degradation of microcystin-LR are investigated in terms of molecular structure. Some suggestions about addition of strongly oxidizing species and problems of further study are put forward. It is shown that TiO 2 photocatalysis is a promising technology to destroy trace-level microcystin-LR in drinking-water.
Keywords:microcystin  photocatalysis  titanium dioxide  drinking-water purification
