采用水热法制备了正交相氧化钼，并研究了其除去铜绿微囊藻的性能。通过XRD、IR、TEM等对正交相氧化钼进行表征；通过检测叶绿素a质量浓度、可溶性蛋白质量浓度和钾离子的释放率探究除藻效果。结果表明，合成的α-MoO₃结晶中没有杂质，且其形貌较为规则，具有良好的晶格结构。通过考察不同质量浓度和不同时间下α-MoO₃对铜绿微囊藻的去除性能发现，2.0 g/L的α-MoO₃在作用60 min时去除率即可达到80%以上。在除藻过程中，α-MoO₃未对藻细胞结构造成破坏，从而避免了藻细胞中微囊藻毒素的释放。

Orthogonal phase molybdenum oxide is prepared through hydrothermal method and its performance for removing microcystis aeruginosa is studied.The material sample is characterized by XRD,IR and TEM,and its algae removal effect is explored through checking the mass concentration of chlorophyll a,total mass concentration of soluble proteins and release rate of potassium ion.The results show that α-MoO₃ prepared by hydrothermal method has good lattice structure,no impurities and regular morphology.The removal rate of microcystis aeruginosa by orthogonal phase α-MoO₃ is investigated at different concentrations and at different time.It is found that the removal rate can exceed 80% after it has been treated by 2.0 g·L^-1 α-MoO₃ for 60 min.Moreover,in the process of algae removal,α-MoO₃ does not destroy the structure of algae cells,thus avoiding the release of microcystis from algae cells.
