PURPOSE:To obtain a capsule having high deodorizing effect, adsorbing nicotine and tar, made possible in the colorimetric judgement of an adsorbing state and having an arbitrary diameter, by dripping a solution mixture containing a specific chemical agent such as sodium alginate and pigment to an aqueous calcium solution to encapsulate the same and impregnating the obtained capsule with lithium chloride. CONSTITUTION:Sodium alginate, aluminum sulfate, sodium thiosulfate, citric acid, pigment and city water are stirred to prepare an aqueous solution. Subsequently, an aqueous calcium chloride solution is prepared and the above- mentioned aqueous solution of sodium alginate or the like is dripped on said solution to form a capsule having a cured film to take out the same. Next, this capsule is charged in an aqueous solution lithium chloride or lithium bromide to allowed to stand until sedimented. Thereafter, the above-mentioned capsule is taken out to obtain a deodorant. |
