ことができる浄水化剤に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifying agent, and more particularly, to an organic substance such as residual effective chlorine, 2-methylisoborneol, diosmin or the like, which causes an off-flavor in drinking water such as tap water, and an organic halogen. The present invention relates to a water purification agent capable of simultaneously removing a compound (TOX).

水器が急速に普及した。2. Description of the Related Art In recent years,
The quality of water sources deteriorated due to environmental pollution, and water purifiers for tap water were rapidly spread.

給するものである。[0003] Such a water purifier is a kind of filter filled with activated carbon or ion exchange resin as a water purifying agent. When the water purifier is interposed in a water supply pipe, the residual available chlorine and iron rust in the tap water cause a problem. It purifies water by adsorbing an unpleasant odor such as kalkan odor or kana, and supplies water suitable for drinking.

原性物質となりうるTOX を取り除くためには多量の活性
炭を必要とした。従って水道水中の塩素臭、悪臭の原因
となる有機物及びTOX を同時に少量で除去することがで
きる吸着剤が望まれている。Since activated carbon does not work effectively in many micropores, a large amount of activated carbon was required to effectively remove organic substances causing chlorine odor and malodor and TOX which may be a mutagenic substance. Therefore, an adsorbent capable of simultaneously removing a small amount of organic substances and TOX which cause chlorine odor and bad odor in tap water is desired.

れている。On the other hand, JP-A-60-225688 describes that a water purifier using fibrous chitosan as a filter medium removes trihalomethane-based substances in tap water. Further, Japanese Patent Publication No. 2-52540 describes that heavy metals and organic substances are effectively removed by using activated carbon and a chitin-based substance in combination.

活性炭より少量であっても効果がある。[0010] Chitin is obtained by decalcifying and deproteinizing the shells of arthropods, especially crustaceans such as crabs and shrimps. Chitosan is deacetylated by heat treatment of chitin in a concentrated aqueous solution of caustic soda. Highly deacetylated chitosan is soluble in dilute hydrochloric acid and dilute acetic acid, but hardly soluble in water near neutrality. However, when used in a swollen form, its constituent glucosamine has the effect of reducing hypochlorous acid, which causes the odor of lime, to make it odorless, and its use amount is smaller than that of conventional activated carbon. effective.

The mouth was closed to obtain a water purifier (product of the present invention). Similarly, water purifiers containing 2 g of granular activated carbon, 2 g of chitosan, and 2 g of copolymer as water purifying agents were produced (Comparative products 1 to 3). Residual chlorine concentration 1.5ppm, mold odor model substance 2-methylisoborneol 0.05ppb, total organic chlorine compound (TOX) 100
The water purifier prepared above was put into 5 liters of model drinking water containing ppb, stirred with a magnetic stirrer for 30 minutes, and immediately thereafter, the water purifier was taken out with tweezers. For the remaining water, the residual chlorine concentration was determined by o-tolidine colorimetric analysis, and the 2-methylisoborneol concentration was extracted at a rate of 50 ml of hexane per liter of water. The hexane phase was concentrated by heating to 1 ml under reduced pressure and concentrated. GC / MS 597 manufactured by Yokogawa Hewlett-Packard Co., Ltd.
It was quantified by performing the analysis at 1 A. TOX was quantified using a chlorine / sulfur analyzer TSX-10 (manufactured by Mitsubishi Chemical Corporation). The removal rate was determined from the results, and is shown in Table 1.

除去できる。(Results) The water purifier using only activated carbon had a high chlorine odor removal rate, but a low mold odor removal rate, and TOX was not removed at all. Further, a water purifier comprising only one of chitosan and a copolymer could not simultaneously remove chlorine odor and mold odor. On the other hand, the water purifier using the water purifier of the present invention can simultaneously remove chlorine odor, mold odor and TOX.
