摘　　要：CaO_(2)纳米粒子作为一种H_(2)O_(2)的替代品,制备较为简单,且应用广泛,在通过芬顿反应等机制治理环境污染方面扮演着重要的角色。但由于CaO_(2)与水反应产生H_(2)O_(2)和O_(2)的速率较快,通常需要在其表面包裹一层高分子材料,作为缓释剂。本文主要介绍了不同的制备CaO_(2)纳米粒子的方法以及过程中使用到的不同缓释剂,总结了CaO_(2)纳米粒子与细菌、Fe^(2+)、O_(3)等联用处理不同污染物(三氯乙烯、土霉素、芳烃污染物、重金属等)的应用进展。As a substitute for H_(2)O_(2),CaO_(2) nanoparticles are simple to prepare and widely used.It plays an important role in controlling environmental pollution through Fenton reaction and other mechanisms.However,because CaO_(2) reacts with water to produce H_(2)O_(2) and O_(2) at a faster rate,it is usually necessary to wrap a layer of high molecular material on its surface as a sustained release agent.This paper mainly introduces different preparation methods of CaO_(2) nanoparticles,different sustained release agents used in the process,and the application progress of CaO_(2) nanoparticles combined with bacteria,Fe^(2+),O_3,etc.,to treat different pollutants,including trichloroethylene,oxytetracycline,aromatic pollutants,heavy metals.
