A method for making a slow releasing device for slowing releasing chlorine dioxide includes sending gaseous chlorine dioxide into a receiving container containing a plurality of particulate carriers. Each particulate carrier has a plurality of pores in a surface thereof. The receiving container is placed in a low-temperature environment below 30° C. The gaseous chlorine dioxide is absorbed by the particulate carriers. The particulate carries is packaged in at least one container that is subsequently sealed. The gaseous chloride dioxide can be purified before entering the receiving container. Superfluous chloride dioxide can be dissolved or absorbed in water in an absorbing tank on a circulating pipeline connected to the receiving container via an outlet pipe. |
