国内、外ClO_2的制造和应用发展状况不很平衡,现祥细描述ClO_2的物理、化学性质;介绍它在消毒、漂白行业的应用及应用效果,并与Cl_2消毒,漂白进行比较进而阐述ClO_2所存在的优点,在生产方面主要阐述几种以NaClO_3为基本原料,以氧化还原反应为原理的化学方法,其中对R_8法进行较为详细的描述,最后将近期国内、外ClO_2的生产和应用情况进行比较,并认为国内研制开发和应用ClO_2是非常必要和紧急的。 The production and application development status of ClO_2 at home and abroad is not well balanced. The physical and chemical properties of ClO_2 are described in detail. The application and application effects of ClO_2 in the disinfection and bleaching industries are introduced. The ClO_2 solution is compared with Cl2 disinfection and bleaching. The existing advantages are mainly explained in the production of several chemical methods based on NaClO 3 as the basic raw material and the principle of redox reaction. The R 8 method is described in more detail. Finally, the production and application of ClO 2 at home and abroad are performed. Comparison, and that domestic research and development and application of ClO_2 is very necessary and urgent.
