PURPOSE:To enable the storage of a solid chlorination agent stably for a long period, by kneading, granulating and drying a mixture of activated carbon and an aluminosilica gel, and placing the obtained granule as a stabilizing agent in an atmosphere surrounding the chlorination agent or a composition containing the chlorination agent. CONSTITUTION:100pts.wt. of an aluminosilica gel of formula (m is 1-2; n is 2-3) prepared by purifying, dehydrating and drying allophen which is an amorphous hydrated silicate of aluminum is mixed with 5-300pts. of activated carbon, and the mixture is kneaded, granulated and dried to obtain a granular stabilizer for a solid chlorination agent such as di-trichloroisocyanuric acid, etc. The stabilizer is placed in an atmosphere surrounding said chlorination agent or a composition containing the chlorination agent, preferably in a state contacting with said atmospheric gas while preventing the direct contact with said chlorination agent. The chlorination agent can be stored stably and extremely safely in a sealed state for a long period.
