title: Rapid catalytic microwave method to damage Microcystis aeruginosa with FeCl3-loaded active carbon.
abstract: In recent years, effective methods for cyanobacterial blooms treatment have been an important issue. In this study, we demonstrated a rapid catalytic microwave method to deal with Microcystis aeruginosa with FeCl(3)-loaded active carbon. Microcystis aeruginosa damage process was monitored by measuring optical density, chlorophyll-a content, superoxide dismutase activity, l-glutathione content, and turbidity of the treated Microcystis aeruginosa suspension. It was found that this method could quickly and efficiently induce the degradation of Microcystis aeruginosa. On the basis of control experiments and characterization results, we attributed the excellent catalytic performance to the synergy effect between hole-doping of the catalyst and hot spot of microwave irradiation. This work provides a fast and green treatment method for cyanobacterial blooms.
