摘　　要：介绍了氧气、双氧水和臭氧这3种清洁氧化剂在湿法冶金领域中材料制备方面的研究应用现状。氧气氧化能力较弱,常用来制备铁化合物和锰化合物功能材料以及焦锑酸钠,利用氧气氧化时通常使用高温高压来增强氧化效果。双氧水的氧化能力较氧气较强,而且在液相中的传质效率较高,其在材料制备方面的应用与氧气相似,但是其应用范围较氧气较大,除了铁氧化物、焦锑酸钠的制备,还可用于其他功能材料的制备。臭氧的氧化能力极强,可以氧化较难氧化的银、钴、镍等离子,目前已有少量材料制备的研究报道。The research status and application for oxygen, hydrogen peroxide and ozone in the preparation of materials in hydrometallurgy are introduced. Due to its mild oxidation ability, oxygen is used to prepare iron com- pounds, manganese compounds, functional materials and sodium pyroantimonate. When oxidated with oxygen, high temperature and pressure is used to enhance the oxidative effect. The oxidation ability of hydrogen peroxide is strong relatively to oxygen, and its mass transfer efficiency is higher. The application in preparation of materials is similar to oxygen,however the range of applications is larger, not only iron oxide, sodium pyroantimonate, but also for other functional materials. Ozone can oxidize silver, cobalt, nickel, which is difficult to be oxidized. At present, a small amount of research reports material prepared with ozone.
