 Abstract
Cyanobacterial toxins, microcystins which exist in korean lakes show strong toxicity to fish, cattles and human. In this study, we tried to degrade microcystin LR using various chemical oxidants, Chlorine, Potassium permanganate and Hydrogen Peroxide. The detection method for the concentrations of microcystin LR in water samples was Enzyme-Linked Immunosorbent Assay (ELISA) method using the monoclonal antibody of microcystin. Chlorine degraded microcystin LR effectively at the concentration of 800 pg/mL microcystin LR and 12 ppm chlorine. The reaction took 40 minutes at pH 7. Potassium Permanganate also degraded microcystin LR successfully at the concentration of 2000 pg/mL microcystin LR and 1.2 ppm chlorine. The degradation reaction took 60 minutes at pH 7. In the case of hydrogen peroxide, the degradation rate of microcystin LR was very slow because of the slow reaction rate.
