Cu2ONPs/DIATOMITE INHIBITS GROWTH AND REMOVAL OF MICROCYSTIS AERUGINOSA

Cu2O nanoparticles (Cu2ONPs) with particle size of ~27.4 nm deposited on diatomite (Cu2ONPs/diatomite), a new low-cost material has been used to investigate growth inhibit, and bloom preventation cyanobacteria in eutrophic waters. Diatomite collected from natural mines was also the experiments. Microcystis aeruginosa strain originated Bac Lieu shrimp pond isolated cultured Z8 medium. Experiments were conducted by exposing M. Cu2ONPs/diatomite at concentrations 0.1, 0.2, 0.5 g/L for 72 hours 120 hours. The results showed that concentration hours, more effective inhibiting removing cells than diatomite. Therefore, could be as promising cyanobacterial water aquaculture.
