摘　　要：缓释型固体二氧化氯因其释放周期较长、稳定性强、释放速率可控等特点迅速发展为二氧化氯消毒领域一个新的研究热点。它采用多孔高分子聚合物作为吸附载体,利用载体的高吸附性能对稳定性二氧化氯溶液或亚氯酸钠溶液及活化酸进行吸附,释放出的二氧化氯气体因载体内部多孔交联结构的阻滞作用达到缓释效果。分析缓释型固体二氧化氯缓释机理,论述其现有制备方法及缓释控制技术,并对其主要应用领域加以综述,指出现有缓释型固体二氧化氯存在的问题及发展前景的展望。Sustained release solid chlorine dioxide has the advantages of prolonged release, strong stability-, controlled release rate, and has rapidly developed into a new research hotspot in the field of chlorine dioxide disinfection. It uses a porous polymer as an ad- sorption carrier, and utilizes the high adsorption capacity of the carrier to adsorb stable chlorine dioxide solution or sodium chlorite solution and activated acid. The release of chlorine dioxide gas is controlled by the porous cross-linked structure of the carrier to achieve the sustained release effect. Release mechanisn of sustained release solid chlorine dioxide is analyzed. Its existing preparation method and sustained release control technology are expounded, and its main fields of application are summarized. Besides, the existing problems and prospects of the available sustained release solid chlorine dioxide are also listed.
