Chlorination of Microcystis aeruginosa: Toxin release and oxidation, cellular chlorine demand and disinfection by-products formation

► Cumulative chlorine demand per number of lysed cells equals 5.6 ± 0.2 pgCl2/cell. ► Significant influence of cellular debris on estimation of chlorination kinetics. ► Successive reaction kinetics modeling of toxins release-oxidation in chlorination. ► Modest contribution of high cell numbers to disinfection by-product precursors pool.
