摘要：

Cyanobacterial blooms have become a serious environmental threat throughout the world. In addition, many cyanobacteria can produce microcystins (MCs), which can threaten human and ecosystem health. Therefore, the removal of Microcystis aeruginosa cells and MCs is essential. In the present work, a modified shrimp shell adsorbent was developed for the removal of M. aeruginosa cells and MCs. The influencing factors of the modified adsorbent on M. aeruginosa removal, including the sodium hydroxide amount, the reaction time and the reaction temperature, were investigated. Under optimal conditions, the removal efficiency of the modified adsorbent toward M. aeruginosa cells was 79.73%, and the adsorbing capacity of the modified adsorbent toward MCs was 100 mu g/g. Therefore, the modified shrimp shell adsorbent is an effective technology and has the potential to remove M. aeruginosa cells and MCs from surface water.
